- Centralize external-profile read-only behavior in a shared Yomitan profile policy
- Clear parser/extension runtime state via dedicated helpers on load failures and reloads
- Prevent opening Yomitan settings when the Yomitan session is unavailable
- Add focused runtime-policy and state-clearing regression tests
- Return status from `openYomitanSettings` and show user-facing warning when external read-only profile mode blocks settings
- Thread `yomitanSession` through settings runtime/opener deps so settings window uses the active session
- Expand tests for session forwarding and external profile path propagation
- Move AniList setup/token/CLI docs into the AniList section in configuration docs
