chore: bump version references in Plugin.cs and README

Pre-push grep-verification found four stale v1.4.3 mentions outside the
Slim-Rule history files:

- Plugin.cs schema-gate error message referenced v1.4.3 by name in both
  the comment and the user-facing exception text. Schema stays at v16,
  but the message now points at the current release
- README.md latest-release badge bumped to v1.4.4
- README.md version header bumped to v1.4.4
- README.md Project Status block rewritten for v1.4.4 with the threading
  and IPC safety items as the lead

ROADMAP.md historical references to v1.4.3 are intentional (released-tag,
foundation-reference) and stay.

 ## Project Status
 
-**Version 1.4.3** — Plugin-load async init plus repo cutover: the plugin has been migrated to Dalamud's
-`IAsyncDalamudPlugin` API. The constructor now handles only bootstrap essentials (config load, language init, conflict
-detection); migrations, service allocations, window construction, and hook subscriptions move into `LoadAsync`, allowing
-Dalamud to keep the UI responsive during heavy lifting. A schema gate replaces the v9 → v16 migration chain; configs at
-schema v16+ load directly, older configs trigger an "install v1.4.2 first" error message. Custom repo URL migrated to
-`gitea.hellion-forge.cloud`; the GitHub repo remains as a frozen v1.4.2 snapshot. Plugin load time is ~3.7 s median (5
-reloads), comparable to v1.4.2 — the async migration is the foundation for v1.4.4 lazy-init optimizations, not a direct
-user-facing win. Fourth sub-patch of the v1.4.x polish sweep series (as of 2026-05-08).
+**Version 1.4.4** — Threading and IPC safety polish on top of the v1.4.3 async-load foundation. The
+`AutoTellTabsService` hot-path getter now reads from an `Interlocked` counter instead of taking a lock on every
+render frame, with a resync hook for the snapshot-restore path in `SaveConfig` and a pure-helper test mirror in the
+Build-Suite repo. The Honorific integration carries per-method threading banners so the framework-thread invariant is
+visible at the call site, and an unsubscribe failure now logs at Warning instead of Debug — a leaked subscription
+across plugin reloads is exactly the kind of thing that should not be silent. The AutoTranslate warmup thread is
+finally marked `IsBackground = true`, matching the pattern used in `MessageManager` and `Plugin.RetentionSweep` since
+v1.4.0. The privacy filter logs once per unknown ChatType so a future patch's added channel does not drop off the
+radar, and new installs default `PrivacyPersistUnknownChannels` to `true` as a failsafe; existing configs keep their
+explicit choice. No schema bump, no migration. Fifth sub-patch of the v1.4.x polish sweep series (as of 2026-05-12).
 
 Hellion Chat is a standalone plugin, no longer a fork in the repository sense. Fully completed:
