Bump to 0.3.1 with the upstream emote regression fix

Quick patch release. The previous commit on this branch is a
straight cherry-pick of Infi's upstream "Fix a regression from
API 15 updates" (ff899ff), which restores BetterTTV emote
deserialisation by switching the Emote and Top100 DTOs from
public fields to public properties so System.Text.Json picks up
the [JsonPropertyName] attributes correctly.

Without this, a fresh Hellion Chat install would happily fetch
emote JSON from BetterTTV but every entry would deserialise to
empty defaults, leaving the cache silently empty.

Manifest version bumps from 0.3.0 to 0.3.1 in csproj, the
HellionChat.yaml manifest plus its changelog, the custom-repo
repo.json (assembly version, testing assembly version and the
three download links), and the README version banner. The 0.3.0
changelog entry stays underneath in chronological order.

Build (Release) verified clean.

 changelog: |-
+  **Hellion Chat 0.3.1 — Upstream emote regression fix**
+
+  Cherry-picks Infi's upstream commit ff899ff "Fix a regression
+  from API 15 updates" which changes the BetterTTV emote DTOs
+  (Emote and Top100) from public fields to public properties.
+  System.Text.Json under the API 15 toolchain only honours the
+  [JsonPropertyName] attribute on properties, so the previous
+  field-based version deserialised every fetched emote into empty
+  default values. Result: BetterTTV emotes were silently broken
+  on fresh installs. The fix is six lines and applies cleanly on
+  top of our defensive null-check from earlier; the EmoteCache
+  path-traversal hardening from 0.3.0 stays as it is.
+
+  Authorship of the fix is preserved with git cherry-pick -x, so
+  Infi shows up as the author on the commit. Thanks to him for
+  catching it in the upstream codebase.
+
+  **Hellion Chat 0.3.0 — Audit hardening, brand sweep and rebrand of slash commands**
+
+  This release closes the remaining audit follow-ups from the
+  0.2.0 cleanup and finishes turning Hellion Chat into a properly
+  branded fork rather than a Chat 2 with a different name.
+
+  Slash commands have been renamed across the board so they no
+  longer collide with the upstream plugin and tell you which
+  plugin owns them at a glance:
+
+  - /chat2          becomes /hellion
+  - /chat2Viewer    becomes /hellionView
+  - /clearlog2      becomes /clearhellion
+  - /chat2Debugger  becomes /hellionDebugger (internal)
+  - /chat2SeString  becomes /hellionSeString (internal)
+
+  This is a breaking change for anyone with macros bound to the
+  old command names. The upstream Chat 2 commands keep working
+  if you also have that plugin installed.
+
+  Privacy and storage hardening based on the post-0.2.0 audit:
+
+  - Privacy filter master switch now states explicitly that the
+    filter only governs storage, not the live chat log
+  - Emote cache refuses to write outside its own directory if a
+    third-party API ever returns a path that escapes
+  - Retention sweep is serialised so the 24h auto-sweep and the
+    manual button cannot launch in parallel and race for the
+    SQLite connection
+  - DbViewer paging uses an int constant and the matching SQL
+    parameter name (the upstream code passed a float and a name
+    without the parameter prefix; both worked in practice but
+    were inconsistent)
+
+  Visual identity now matches the Hellion Online Media website:
+
+  - Theme palette switched to Arctic Cyan plus Ember Orange,
+    matching the website's BRANDING.md tokens
+  - Active tabs and window title bars use a brand-color-dark teal
+    variation as identity colour, replacing the previous slate
+    violet that did not appear in the brand
+  - Resize grips and scrollbar grabs picked up Ember Orange
+    instead of industrial amber on hover and active states
+
+  About tab rewritten and properly localised:
+
+  - New "Why this fork exists" block sets out the mission in
+    neutral terms, framing Chat 2's full-history default as the
+    right one for most users while explaining the narrower
+    default footprint this fork chose
+  - All Hellion-specific About copy now lives in HellionStrings
+    in EN and DE, so German users see the Hellion sections in
+    German rather than the upstream English fallback
+  - Webinterface absence is described as a focus mismatch
+    (different use case, substantial rebuild) rather than as
+    a security issue with the upstream code
+  - Translator list at the bottom of the About tab is reachable
+    again on smaller settings windows
+
+  Based on Chat 2 1.35.3 (upstream Infiziert90/ChatTwo, EUPL-1.2).
+
   **Hellion Chat 0.2.0 — Webinterface removed**
 
-  Following an internal security and consistency audit the upstream
-  webinterface has been removed in its entirety. Hardening it to the
-  privacy guarantees Hellion Chat makes by default would have meant
-  rewriting the auth flow (the upstream code uses a five-digit
-  numeric code from System.Random), changing the default bind address
-  (currently every interface), reworking cookie handling and adding
-  the privacy filter to the live message stream that the webinterface
-  was broadcasting around it. The cumulative cost did not match the
-  niche use case for a fork that wants less network surface, not more.
+  The upstream webinterface has been removed in its entirety. It
+  serves a different use case from the smaller default footprint
+  this fork is built around, namely remote access to chat from a
+  second device. Aligning it with the data minimisation defaults
+  Hellion Chat ships with would have meant a substantial rebuild.
+  Removing it was the cleaner path for this particular fork.

+    <value>Hellion Chat is not trying to replace Chat 2. Chat 2 ships a complete chat experience with full history available for filtering, search and replay.

After two years on Chat 2 my database had grown past two million messages, most of them /say, /shout and /yell from strangers in Limsa. That data is exactly what makes Chat 2's full-history view powerful and most users are happy to keep it. For my own taste I wanted a smaller default. So I built this fork.</value>

 Hellion Chat baut auf Chat 2 auf und ergänzt es um Datenschutz- und Daten-Handling-Kontrollen, die mit den Datenschutz-Regeln in der EU, den USA und Japan im Einklang sind. Alle Chat-2-Funktionen, Befehle und Tastenkürzel funktionieren unverändert. Eigenständiger Plugin-Slot, eigene Konfiguration, eigene Datenbank.

 ### Was gegenüber Chat 2 fehlt
 
-- **Webinterface** wurde in Hellion Chat 0.2.0 entfernt. Der eingebaute HTTP-Server hat unter dem Privacy-Versprechen nicht abgesichert werden können (5-stelliger numerischer Auth-Code aus `System.Random`, Bind auf alle Interfaces per Default, Cookies ohne Security-Flags und ein Server-Sent-Events-Stream der den Privacy-Filter umgangen hat). Wer den Funktionsumfang von Chat 2 vollständig braucht, sollte beim Upstream-Plugin bleiben; Hellion Chat fokussiert auf DSGVO-konforme Persistenz und verzichtet bewusst auf Remote-Zugriffs-Features.
+- **Webinterface** wurde in Hellion Chat 0.2.0 entfernt. Es bedient einen anderen Anwendungsfall als der Fokus dieses Forks, nämlich Remote-Zugriff auf den Chat von einem zweiten Gerät. An die kleineren Defaults dieses Forks anzupassen hätte einen erheblichen Umbau bedeutet, also ist es ersatzlos entfernt worden. Wer den vollen Funktionsumfang von Chat 2 möchte, ist mit dem Upstream-Plugin besser bedient. Hellion Chat fokussiert sich auf einen schmaleren Datenbestand und verzichtet bewusst auf Remote-Zugriffs-Features.
