fix: CI changelog, annotation options threading, and Jellyfin quit

- Add `type: fixed` / `area:` frontmatter to `changes/319` to pass `changelog:lint`
- Thread `TokenizerAnnotationOptions` through `stripSubtitleAnnotationMetadata` so `sourceText` is honored
- Include `jellyfinPlay` in `shouldQuitOnDisconnectWhenOverlayRuntimeInitialized` predicate
- Make mouse test `elementFromPoint` stubs coordinate-sensitive
- Make Lua test `.tmp` mkdir portable on Windows
