fix: crash prevention and stability improvements

Critical Fixes:
- Exit handler: Replace nested tokio runtime with separate thread + timeout
  to prevent "Cannot start a runtime from within a runtime" panic
- Pill window: Add safe screen query helpers with proper MainThreadMarker
  handling to prevent crashes on multi-monitor setups
- Settings cache: Switch from std::sync::RwLock to parking_lot::RwLock
  to eliminate lock poisoning issues
- Tray menu: Make rebuild_tray_menu async to avoid runtime conflicts
- Add tray menu sync when language/microphone changed from UI

Recorder Improvements:
- Improve thread join with timeout and safe panic message extraction
- Better error handling for audio stream errors with context
- Add proper cleanup when consumer thread times out

State Machine:
- Add retry loop with backoff for compare-exchange operations
- Better handling of race conditions during state transitions
- More informative error messages for debugging

Other:
- Fix ESLint warning in analytics provider
- Add debug logging for tray menu rebuild operations
