feat: Implement DeepWiki generator and CLI integration

- Added `deepwiki_generator.py` for generating documentation from source code.
- Integrated symbol extraction and markdown generation for supported file types.
- Implemented database migration for legacy timestamp formats in DeepWikiStore.
- Enhanced debug logging for better traceability during conversation and store operations.
- Updated dependencies in `PKG-INFO` and `requires.txt` for compatibility.
- Added new tests for the DeepWiki generator and storage functionalities.
- Refactored existing code for improved readability and maintainability.
