feat: Implement DeepWiki documentation generation tools

- Added `__init__.py` in `codexlens/tools` for documentation generation.
- Created `deepwiki_generator.py` to handle symbol extraction and markdown generation.
- Introduced `MockMarkdownGenerator` for testing purposes.
- Implemented `DeepWikiGenerator` class for managing documentation generation and file processing.
- Added unit tests for `DeepWikiStore` to ensure proper functionality and error handling.
- Created tests for DeepWiki TypeScript types matching.
