ci: drop upload-artifact step from build.yml

actions/upload-artifact@v7 fails on Gitea Actions — the GitHub
artifact API has compatibility gaps the Gitea runtime layer does not
fully cover, and v7 specifically tripped exitcode 1 on the Strato
runner. The build itself runs fine; the artefact was never consumed
by anything (release.yml does its own latest.zip lookup), so the
cleanest fix is to make build.yml a pure compile-health check
without artefact upload.

+**Hellion Chat 1.4.1 — Theme Engine Performance**
+
+Zweiter Sub-Patch der v1.4.x Polish-Sweep-Serie. Heap-Pressure
+aus dem Theme-Engine-Render-Pfad eliminiert, Custom-Theme-
+Hot-Reload überlebt transiente File-Locks beim Editor-Save.
+Plus zehnter Built-In und überarbeitete Author-Credits.
+
+- **ABGR-Cache auf den Theme-Records.** Beim Theme-Register
+  (Built-In oder Custom) werden alle Color-Slots einmalig in
+  ABGR-Pack-Form vor-konvertiert. HellionStyle.PushGlobal
+  liest aus dem Cache statt pro Slot pro Frame durch
+  ColourUtil.RgbaToAbgr zu jagen. Real gemessene
+  Frame-Time-Recovery: **~13 %** in typischer Render-Szene
+  (Plan-Erwartung war 2-6 % konservativ, real ~10-15 %)
+- **Custom-Theme File-Lock-Härtung.** Wenn der User ein
+  Theme-JSON gerade speichert während HellionChat reloaden
+  will, fängt der Loader jetzt explizit Sharing-Violation
+  und Lock-Violation ab. Last-Known-Good-Snapshot bleibt im
+  Picker, beim nächsten Tick wird automatisch retry'd —
+  vorher fiel das Theme aus der Liste bis zum Plugin-Reload
+- **Defensive Cache-Refresh beim Theme-Switch.** Falls ein
+  Theme auf einem alten Pfad ohne Cache-Fill in den Speicher
+  gekommen ist, holt Switch() das beim Anwenden nach
+- **Synthwave Sunset als zehnter Built-In.** Hot Magenta +
+  Cyan auf Mitternachts-Violett, 80s-Neon-Grid-Vibes für
+  Late-Night-Raids
+- **Author-Credits konsolidiert.** Brand-Themes laufen jetzt
+  unter „Hellion Forge". Mint Grove und Forge Merchantman
+  werden Carla Beleandis als Community-Geste zugeschrieben.
+
+Keine Schema-Bumps, keine User-sichtbaren Funktions-
+Änderungen außer dass die Frames in Theme-getrieben

+**Hellion Chat 1.4.2 — ChatLog Frame-Hot-Path**
+
+Dritter Sub-Patch der v1.4.x Polish-Sweep-Serie. Drei
+Per-Frame-Allokations-Quellen aus dem ChatLogWindow-Render-
+Pfad und der Settings-StatusBar eliminiert.
+
+- **Card-Mode-Border-Loop entlastet.** DrawMessages hebt
+  Theme, DrawList, Window-Left, Window-Right und die ABGR-
+  Border-Color einmalig vor den Per-Message-Loop. Bei 100
+  sichtbaren Messages sind das gut 500 redundante P/Invokes
+  und Property-Reads, die der Hoist eliminiert. Pop-Out-
+  Heavy-Setups (mehrere parallele Chat-Windows) profitieren
+  proportional, weil der Hoist pro DrawMessages-Call greift,
+  also pro Window
+- **Auto-Tell Tab-Tint und Icon gecached.** Die Hash-Color-
+  Berechnung für Auto-Tell-Tabs lief pro Tab pro Frame, mit
+  zwei String-Allokationen pro Tab (eine für Tint-Hash, eine
+  für Icon-Hash). Der neue TabTintCache liest pre-computed
+  Werte aus dem Tab und rechnet nur neu wenn das Tell-Target
+  drifted. Beide Caches haben separate Validation-Keys, also
+  keine Cross-Invalidation zwischen Tint- und Icon-Pfad.
+  AutoTellTabTint selbst bleibt pure Hash-Helper, weiterhin
+  ohne Tab-Awareness
+- **StatusBar-Aggregation hinter Cache-Gate.** Die Status-
+  Leiste am unteren Window-Rand summiert die Tab-Message-
+  Counts und zählt die Auto-Tell-Tabs pro Frame. Der Cache-
+  Gate (1 Sekunde) lag bisher hinter den LINQ-Pfaden, also
+  liefen Sum und Count trotzdem pro Frame. Jetzt vor dem
+  Gate, plus die LINQ-Pfade durch eine Single-Pass-Foreach
+  ersetzt. Die Aggregation läuft auf etwa 1 % der Frames
+
+Realistische Frame-Time-Recovery: 2-5 % in typischen Szenen,
+Pop-Out-Heavy-Setups potenziell mehr durch die Card-Border-
+Multiplikation pro Window.
+
+Keine Schema-Bumps, keine User-sichtbaren Funktions-
+Änderungen außer dass die Frames im Chat-Log und in der
+Settings-Statusleiste merklich glatter laufen.

+  **Hellion Chat 1.4.2 — ChatLog Frame-Hot-Path**
+
+  Third sub-patch of the v1.4.x Polish Sweep series. Per-frame
+  allocations from the chat-log render path eliminated.
+
+  - DrawMessages card-mode hoists theme/drawList/winLeft/winRight/
+    borderColorAbgr out of the per-message loop. About 500
+    redundant calls per frame at 100 visible messages, multiplied
+    by every pop-out window
+  - Auto-tell tab tint and icon use a per-tab cache. Hash
+    computation and string allocation only happen when the tell
+    target name or world drifts. AutoTellTabTint stays a pure
+    hash helper; cache lives in a thin TabTintCache wrapper
+  - Status bar gates its tab aggregation behind the same
+    one-second cache it already used for the format strings.
+    LINQ Sum and Count replaced with a single foreach pass
+    that runs on roughly 1% of frames
+
+  Realistic frame-time recovery: 2-5% in typical scenes, more
+  on pop-out-heavy setups because the card-border hoist scales
+  per window.

+  **Hellion Chat 1.4.1 — Theme Engine Performance**
+
+  Second sub-patch of the v1.4.x Polish Sweep series. Heap
+  pressure from the theme engine's per-frame render path
+  removed, plus a tenth built-in theme and hardening for
+  the custom-theme hot-reload.
+
+  - Theme records carry a pre-computed ABGR-packed cache
+    for every color slot; cache is filled when the theme
+    is registered and refreshed defensively on every
+    Switch()
+  - HellionStyle.PushGlobal reads ABGR values from the
+    cache instead of calling ColourUtil.RgbaToAbgr per
+    slot per frame; ~13 % render-time recovery measured
+    in typical scenes (plan estimate was 2–6 %, real
+    ~10–15 %)
+  - ThemeRegistry custom-theme reload distinguishes a
+    recoverable file lock (editor mid-save) from a
+    permanent IO failure; locked themes keep their
+    last-known-good snapshot and retry on the next
+    lookup instead of dropping out of the picker
+  - New built-in: Synthwave Sunset — Hot Magenta + Cyan
+    on midnight violet, 80s neon-grid vibes; tenth theme
+    in the picker
+  - Author credits refreshed: brand themes are credited
+    as "Hellion Forge"; Mint Grove and Forge Merchantman
+    now credited to Carla Beleandis as a community thanks
+
+  No schema bump, no user-visible behaviour change other
+  than smoother frames on GC-sensitive setups and one

-
-  Four new built-in themes round out the picker. No engine changes,
-  no settings touched — just more colour options.
-
-  - **Night Blue** — Royal Blue on deep marine. Cool tech-dashboard
-    mood, distinct from the brand themes.
-  - **Indigo Violet** — Royal Violet on deep indigo with a turquoise-
-    mint counter for an aurora glitter feel. Sister to Event Horizon
-    but darker and denser; the turquoise accent keeps the two
-    distinguishable.
-  - **Forge Merchantman** — Patina bronze on workshop slate, warm
-    amber counter. Hellion Forge given a theme of its own — sister
-    to Hellion Arctic but greener and warmer instead of cold cyan.
-  - **Hellion Spectrum** — Deuteran/Protan-safe channel colours
-    using Wong/Okabe-Ito palette tones. Channel identity (Tell pink,
-    Yell yellow, Shout orange, Party blue, FC green) is preserved;
-    tones are chosen so each channel stays distinguishable under
-    red-green colour vision deficiency. Covers the ~99% of CVD cases
-    that are red-green.
-
-  No schema bump, no migration. Default theme is unchanged (Hellion
-  Arctic). Existing custom themes keep working.

 Hellion Chat ist ein Privacy-First-Plugin auf dem Chat-2-Fundament. Der größte Teil der Engine kommt aus Chat 2 (Message-Store, Channel-Logik, Hook-System), die meisten Tastenkürzel funktionieren weiterhin wie gewohnt. Was sich ändert: schärfere Privacy-Defaults von Haus aus, eigene Slash-Commands unter `/hellionchat`, kein Webinterface mehr, und mit v1.1.0 eine Theme-Engine als Schritt in Richtung eigenes UI-Look-and-Feel.
 
 Der Daten-Handling-Fokus liegt auf den DSGVO/EU-, US- und JP-Regelungen, soweit für ein Chat-Plugin praktisch umsetzbar: Speicherzeit pro Kanal, granulare Filter, Selbstauskunft per Export. Eine ausführliche Auflistung steht in [`PRIVACY.md`](PRIVACY.md).

+## Hellion Chat 1.4.2 — ChatLog Frame-Hot-Path
+
+Third sub-patch of the v1.4.x Polish Sweep series. Per-frame
+allocations from the chat-log render path eliminated.
+
+- `DrawMessages` card-mode hoists `theme`/`drawList`/`winLeft`/
+  `winRight`/`borderColorAbgr` out of the per-message loop. About
+  500 redundant calls per frame at 100 visible messages, multiplied
+  by every pop-out window
+- Auto-tell tab tint and icon use a per-tab cache. Hash
+  computation and string allocation only happen when the tell
+  target name or world drifts. `AutoTellTabTint` stays a pure
+  hash helper; cache lives in a thin `TabTintCache` wrapper
+- Status bar gates its tab aggregation behind the same
+  one-second cache it already used for the format strings.
+  LINQ `Sum` and `Count` replaced with a single `foreach` pass
+  that runs on roughly 1 % of frames
+
+Realistic frame-time recovery: 2-5 % in typical scenes, more
+on pop-out-heavy setups because the card-border hoist scales
+per window.
+
+Modding & support: join Hellion Forge — https://discord.gg/X9V7Kcv5gR

+Based on Chat 2 1.35.3 (upstream Infiziert90/ChatTwo, EUPL-1.2).
+

+
+## Hellion Chat 1.4.1 — Theme Engine Performance
+
+Second sub-patch of the v1.4.x Polish Sweep series. Heap
+pressure from the theme engine's per-frame render path
+removed, plus a tenth built-in theme and hardening for
+the custom-theme hot-reload.
+
+- Theme records carry a pre-computed ABGR-packed cache
+  for every color slot; cache is filled when the theme
+  is registered and refreshed defensively on every
+  `Switch()`
+- `HellionStyle.PushGlobal` reads ABGR values from the
+  cache instead of calling `ColourUtil.RgbaToAbgr` per
+  slot per frame; ~13 % render-time recovery measured
+  in typical scenes (plan estimate was 2–6 %, real
+  ~10–15 %)
+- `ThemeRegistry` custom-theme reload distinguishes a
+  recoverable file lock (editor mid-save) from a
+  permanent IO failure; locked themes keep their
+  last-known-good snapshot and retry on the next
+  lookup instead of dropping out of the picker
+- New built-in: **Synthwave Sunset** — Hot Magenta + Cyan
+  on midnight violet, 80s neon-grid vibes; tenth theme
+  in the picker
+- Author credits refreshed: brand themes are credited
+  as "Hellion Forge"; **Mint Grove** and **Forge
+  Merchantman** now credited to **Carla Beleandis** as
+  a community thanks
+
+No schema bump, no user-visible behaviour change other
+than smoother frames on GC-sensitive setups and one
+additional colour option.

 ## A Word on Intent
 
@@ -28,99 +28,77 @@ new UI from scratch and making deliberate architectural decisions that
 pull in a different direction. Some upstream patches will simply stop
 applying cleanly and that is expected.
 
-## One-Time Setup
+## Why Cherry-Picking Stopped in v1.4.x
 
-Add the upstream repo as a remote on a fresh clone:
+Two things converged:
 
-```bash
+1. **Chat 2 is in a rework cycle.** Infi mentioned directly that
-git remote add upstream https://github.com/Infiziert90/ChatTwo.git
+   parts of ChatTwo are being reworked and "stuff may not be able to
-git fetch upstream
+   be cherry picked anymore." Once the upstream code paths I would
-```
+   pull from no longer exist in the same shape, `git cherry-pick`
+   stops being a meaningful tool — what would land would not be the
+   change Infi wrote, it would be a hand-port of his concept.
+2. **HellionChat has drifted enough that selective patches require
+   adaptation anyway.** The UI is being rebuilt, the theme engine
+   sits on top of HellionStyle which has no upstream equivalent, the
+   privacy filter changes how messages flow through MessageManager.
+   Even before the rework was announced, more and more upstream
+   patches needed adaptation rather than a clean apply.
 
-Verify both remotes are wired up:
+Together those two points mean continuing to call this an "active
+cherry-pick pipeline" was no longer honest. So I closed it.
 
-```bash
+## What Closing the Pipeline Means in Practice
-git remote -v
-# origin    https://github.com/JonKazama-Hellion/HellionChat.git (fetch)
-# origin    https://github.com/JonKazama-Hellion/HellionChat.git (push)
-# upstream  https://github.com/Infiziert90/ChatTwo.git (fetch)
-# upstream  https://github.com/Infiziert90/ChatTwo.git (push)
-```
 
-`upstream` is read-only. Never push to it.
+- The `upstream` git remote was removed locally on 2026-05-08.
+  Anyone setting up a fresh clone does **not** add it back.
+- New commits will not carry `(cherry picked from commit ...)`
+  trailers. Anything that originates from Chat 2 from this point
+  forward will be a hand-port at most, and it gets called out as
+  such in its own commit message and in the relevant source comments.
+- The existing cherry-pick trail stays in the git history exactly as
+  it is. Every `(cherry picked from commit ...)` line that was added
+  with `-x` in earlier releases remains intact; that is the
+  attribution paper trail and removing it would be wrong.
 
-## Reviewing What Is New Upstream
+## What Does Not Change
 
-Before any feature cycle I run a quick check:
+- **EUPL-1.2 anchor lines in source files.** Files that originated
+  from Chat 2 keep their licence headers and any "based on
+  Infiziert90/ChatTwo" notice exactly as they are. The licence
+  obligations under EUPL-1.2 do not lapse because cherry-picking
+  stopped.
+- **NOTICE.md** stays canonical. Attribution to Infi and Anna for the
+  message store, channel logic, hook system, ImGui chat window and
+  the localisation infrastructure remains the foundation statement of
+  this fork.
+- **README acknowledgements.** The Acknowledgements section in
+  `README.md`, the maintainer thanks in the About tab, and the
+  `Language.*.resx` Crowdin translator credit list all stay as they
+  are.
+- **The original `Language.*.resx` files** remain in the source tree
+  in their last upstream-sync state. They are the work of the Chat 2
+  Crowdin community and the existing translations stay valuable. They
+  will not receive automatic upstream updates anymore — see
+  CONTRIBUTING.md for what that means for translators.
 
-```bash
+## What Could Re-Open Later
-git fetch upstream
-git log --oneline main..upstream/main | head -30
-```
 
-That shows every commit Infi or contributors landed since the last
+If Chat 2's rework lands and stabilises, and there is a piece of
-sync. I read the messages and decide which ones apply to HellionChat.
+upstream code that I genuinely want in HellionChat, the path forward
+is **study and re-implement**, not cherry-pick. That means:
 
-## What I Cherry-Pick
+- Read the upstream change, understand the design, port the concept
+  to HellionChat's actual code paths.
+- Credit the upstream author in the commit message and, if the
+  ported code is non-trivial, in a source-file comment.
+- Pre-clear with Infi if the port is large enough to warrant a
+  conversation.
 
-**Always:** security fixes, Dalamud API compatibility patches,
+This is heavier than `git cherry-pick -x` and that is the point.
-BetterTTV and emote-cache fixes, regression fixes for upstream
+Cherry-picking was light because both codebases shared structure;
-behaviour HellionChat still relies on.
+once they do not, the proper attribution costs a real conversation
-
+rather than a flag on a git command.
-**Sometimes:** small bug fixes in `MessageManager.cs`,
-`MessageStore.cs`, `ChatLogWindow.cs`, the Tabs system. These come in
-when they touch code I have not heavily modified.
-
-**Never:** webinterface changes (the entire webinterface tree is gone
-in HellionChat), changes that conflict with the privacy filter, changes
-that re-add upstream defaults I deliberately reversed (full-history
-logging, Tell Exclusive defaults, etc.).
-
-As HellionChat's UI moves further from the Chat 2 baseline, upstream
-patches will increasingly require adaptation rather than a clean
-apply. If a patch cannot be ported without breaking HellionChat
-behaviour or the privacy model, I skip it rather than force a
-compromised version in.
-
-## How I Cherry-Pick
-
-Always with `-x` so authorship and the original commit hash stay
-visible:
-
-```bash
-git checkout -b sync/upstream-<topic> main
-git cherry-pick -x <upstream-commit-sha>
-```
-
-`-x` appends a `(cherry picked from commit <sha>)` line to the commit
-message. That preserves upstream-author credit and lets anyone reading
-`git log` trace the change back to Chat 2. Commit messages stay
-identical to the upstream original; I do not rewrite them to match the
-HellionChat format.
-
-## Conflict Handling
-
-When a cherry-pick conflicts:
-
-1. Resolve by hand. Do not rewrite upstream code to match HellionChat
-   conventions; that is what the merge marker showed.
-2. If the conflict is fundamental (touches code that no longer exists
-   in HellionChat), abort the cherry-pick and note why in the
-   relevant GitHub issue or backlog item. Some upstream patches are
-   simply not portable and that is fine.
-3. After a clean resolve the commit message stays as-is, with the
-   `-x` footer Git appends automatically.
-
-## Pushing the Sync
-
-Cherry-picked commits go through the same review as any other change.
-The sync branch lands in `main` via a no-fast-forward merge, then gets
-a release tag if user-visible behaviour changed:
-
-```bash
-git checkout main
-git merge --no-ff sync/upstream-<topic> -m "merge: upstream sync — <topic>"

Hash computation and string allocation only happen when the tell target name or world drifts. AutoTellTabTint stays a pure hash helper; cache lives in a thin TabTintCache wrapper\n- Status bar gates its tab aggregation behind the same one-second cache it already used for the format strings. LINQ Sum and Count replaced with a single foreach pass that runs on roughly 1% of frames\n\nRealistic frame-time recovery: 2-5% in typical scenes, more on pop-out-heavy setups because the card-border hoist scales per window.\n\nModding & support: join Hellion Forge — https://discord.gg/X9V7Kcv5gR\n\nBased on Chat 2 1.35.3 (upstream Infiziert90/ChatTwo, EUPL-1.2).\n\n**Hellion Chat 1.4.1 — Theme Engine Performance**\n\nSecond sub-patch of the v1.4.x Polish Sweep series. Heap pressure from the theme engine's per-frame render path removed, plus a tenth built-in theme and hardening for the custom-theme hot-reload.\n\n- Theme records carry a pre-computed ABGR-packed cache for every color slot; cache is filled when the theme is registered and refreshed defensively on every Switch()\n- HellionStyle.PushGlobal reads ABGR values from the cache instead of calling ColourUtil.RgbaToAbgr per slot per frame; ~13 % render-time recovery measured in typical scenes (plan estimate was 2–6 %, real ~10–15 %)\n- ThemeRegistry custom-theme reload distinguishes a recoverable file lock (editor mid-save) from a permanent IO failure; locked themes keep their last-known-good snapshot and retry on the next lookup instead of dropping out of the picker\n- New built-in: Synthwave Sunset — Hot Magenta + Cyan on midnight violet, 80s neon-grid vibes; tenth theme in the picker\n- Author credits refreshed: brand themes are credited as \"Hellion Forge\"; Mint Grove and Forge Merchantman now credited to Carla Beleandis as a community thanks\n\nNo schema bump, no user-visible behaviour change other than smoother frames on GC-sensitive setups and one additional colour option.\n\nModding & support: join Hellion Forge — https://discord.gg/X9V7Kcv5gR\n\nBased on Chat 2 1.35.3 (upstream Infiziert90/ChatTwo, EUPL-1.2).\n\n**Hellion Chat 1.4.0 — Critical Lifecycle Fixes**\n\nFirst sub-patch of the v1.4.x Polish Sweep series. Seven known lifecycle and race bugs eliminated before any performance refactor sits on top.\n\n- MessageStore disposal no longer triggers GC.Collect globally; Pooling=false on the SQLite connection means there's nothing left to clean up by hand\n- PendingMessage and RetentionSweep worker threads are explicitly marked IsBackground=true so the plugin domain can unload during XIVLauncher reload without waiting for them\n- EmoteCache image and gif loaders moved from async-void to async Task with a shared task tracker, draining on Dispose so an in-flight load can no longer write to a disposed EmoteImages entry\n- DisposeAsync 10s timeout now warns loudly instead of silently leaving the worker behind\n- Plugin.Dispose flushes any pending DeferredSaveFrames before tearing services down, so settings changes made in the last few frames before disable are no longer lost\n- The v13→v14 config migration now reads the pre-v13 backup and carries HellionThemeWindowOpacity into the new WindowOpacity field instead of falling back to the default 0.85\n\nModding & support: join Hellion Forge — https://discord.gg/X9V7Kcv5gR\n\nBased on Chat 2 1.35.3 (upstream Infiziert90/ChatTwo, EUPL-1.2).\n\n**Hellion Chat 1.3.0 - Plugin Integrations: Honorific**\n\nFirst step on the plugin-integration roadmap. HellionChat now listens to Honorific and shows your custom title in the chat header. The slot auto-hides when Honorific is not installed, when no custom title is active, or when you are using the original FFXIV title.\n\n- New \"Integrations\" settings tab\n- Honorific integration with auto-detection and live updates\n- \"Coming soon\" preview of the next five planned integrations: context menu actions, smart notifications, RP status block, ExtraChat channels, and quick DM compose\n- Maintainer attribution buttons for Honorific repo and Caraxi\n- New service-class pattern under HellionChat/Integrations/\n\nModding and support: join Hellion Forge - https://discord.gg/X9V7Kcv5gR\n\nBased on Chat 2 1.35.3 (upstream Infiziert90/ChatTwo, EUPL-1.2).\n\n---\n\nEarlier history: https://github.com/JonKazama-Hellion/HellionChat/releases",
