CHECKPOINT: Clean 2.0 Architecture - Delegation Pattern Removed

Browse source 
MAJOR ARCHITECTURAL IMPROVEMENTS:
✅ Moved all implementations from private methods into public 2.0 methods
✅ Removed unused private legacy methods (get, delete, getMetadata, update)
✅ Eliminated confusing delegation pattern - direct implementation now
✅ Maintained 100% TypeScript compilation success (0 errors)

PUBLIC 2.0 API METHODS NOW SELF-CONTAINED:
- getNoun() - Contains full retrieval logic
- deleteNoun() - Contains soft delete logic (2.0 default)
- updateNoun() - Contains update logic with vector regeneration
- getNounMetadata() - Contains metadata retrieval logic
- updateNounMetadata() - Contains metadata update logic

BENEFITS:
- Cleaner, more readable codebase
- Direct implementation pattern (no delegation)
- Easier to understand and maintain
- Ready for comprehensive testing

Next: Begin comprehensive testing of all public API methods
