docs: verify and document clean dependency structure

- Verify no cyclic dependencies in processor components
- Document dependency management strategies in systemPatterns.md
- Update activeContext.md with current verification status
- Confirm proper use of TYPE_CHECKING and late initialization

+Verified no cyclic dependencies exist in the codebase (2024 verification)
 
 ## Recent Analysis (2024)
 
 1. Dependency Structure:
    - ✅ No cyclic dependencies found
-   - ✅ processor → utils (one-way dependency)
-   - ✅ shared module properly isolated
-   - ✅ TYPE_CHECKING used correctly
+   - ✅ TYPE_CHECKING used correctly in VideoProcessor
+   - ✅ Clean handler initialization pattern
+   - ✅ Proper dependency direction maintained
 
 2. Key Components:
-   - shared/progress.py handling progress tracking
-   - utils package providing core utilities
-   - processor package consuming utils functionality
+   - VideoProcessor using late initialization
+   - MessageHandler with clean imports
+   - QueueHandler with proper separation
+   - Utils package properly isolated

 ## Next Steps
 
 - Continue monitoring for new cyclic dependencies
-- Consider moving more shared functionality to shared package if needed
+- Consider implementing dependency injection container
 - Maintain current clean architecture patterns
