feat: Consolidate documentation into a single comprehensive guide

- Created `CONSOLIDATED_DOCS.md` to serve as the primary documentation source, integrating user and developer guides, API references, and troubleshooting sections.
- Updated `README.md` to reference the new consolidated documentation.
- Preserved existing documentation files for backward compatibility, including `USER_GUIDE.md`, `DEVELOPER_GUIDE.md`, and others.
- Enhanced navigation structure in `docs/README.md` to facilitate easier access to documentation.
- Implemented UI flickering fixes, including auto-save optimizations, debounced filter updates, and efficient tree updates to improve user experience.
- Added verification script `verify_docs_consolidation.py` to ensure successful documentation consolidation and integrity.
