feat(architecture): add multi-subproject awareness and automatic context resync

- Implemented subproject root resolution based on active editor hint
- Added debounced event listener for active editor changes to trigger chip status updates
- Updated sidebar provider to re-resolve active subproject root on every chip build
- This ensures correct architecture context is injected when working in a monorepo or multi-root-style parent folder
