Add comprehensive tests for keyword detection, session state management, and user abort detection

- Implement tests for KeywordDetector including keyword detection, sanitization, and priority handling.
- Add tests for SessionStateService covering session validation, loading, saving, and state updates.
- Create tests for UserAbortDetector to validate user abort detection logic and pattern matching.
