chore: vscode ruff, and format

Resolved conflicts by keeping enhanced CLI functionality with app discovery:
- Enhanced list_indexes() with _discover_indexes_in_project() supporting both CLI and app formats
- Maintained register_project_directory() function with proper imports
- Updated README.md with comprehensive CLI documentation including type icons
