feat: enhance lesson management and review system

- Added LessonAccept and LessonReject actions to manage lesson outcomes.
- Implemented probe for build/test verification before triggering reviews.
- Introduced a mechanism for recording shadow hits and evaluating trials in the ReviewSystem.
- Enhanced lesson structure with additional fields for scope, snippets, and provenances.
- Updated command parsing to include lesson acceptance and rejection commands.
- Improved session state management with staleness sweeps and retrospective creation.
- Enhanced UI to display detailed usage statistics and quality trends.
