feat: enhance spec loading capabilities and add new categories

- Added support for loading specs from new categories: debug, test, review, and validation.
- Updated various agents and skills to include instructions for loading project context from the new spec categories.
- Introduced new spec documents for test conventions, review standards, and validation rules to improve project guidelines.
- Enhanced the frontend to support new watcher settings and display auto-watch status.
- Improved the spec index builder to accommodate new categories and ensure proper loading of specifications.

 ## Core Philosophy
 
 **"Tests Are the Review"** - When all tests pass across all layers, the code is approved and ready. No separate review process is needed.
