- Remove rate limits imports and handlers from server.py
- Update tools __init__.py to remove rate limits exports
- Update README to reflect 2 tools instead of 3
- Update smithery.yaml configuration
- Update tests to reflect new tool count
- Simplify to essential search and faceting functionality only
