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

+### Current Dependency Chain (Verified 2024)
 
 1. VideoProcessor (core.py)
-   - Imports MessageHandler, QueueHandler, CleanupManager under TYPE_CHECKING
-   - Creates instances of these handlers in __init__
+   - Uses TYPE_CHECKING for handler imports
+   - Late initialization of handlers

 2. MessageHandler (message_handler.py)
-   - Imports ConfigManager, URLExtractor
-   - No circular imports detected
+   - Imports from config, queue, and utils

 ### Mitigation Strategies Used
 
 1. TYPE_CHECKING conditional imports
-   - Used effectively in core.py and cleanup_manager.py
+   - Used effectively in core.py
    - Prevents runtime circular imports
    - Maintains type safety during development
