feat: Enhance documentation diagnosis and category mapping

- Introduced action to diagnose documentation structure, identifying redundancies and conflicts.
- Added centralized category mappings in JSON format for improved detection and strategy application.
- Updated existing functions to utilize new mappings for taxonomy and strategy matching.
- Implemented new detection patterns for documentation redundancy and conflict.
- Expanded state schema to include documentation diagnosis results.
- Enhanced severity criteria and strategy selection guide to accommodate new documentation issues.
