fix: complete web search integration with query enrichment

Fixes several issues with the web search migration to Librarian:

- Update Steward routing guidelines for web search/weather → Librarian
- Register search_web, read_url, read_urls_batch tools with Librarian agent
- Update Librarian system prompt with web search documentation
- Fix query enrichment not being passed to delegations (location context)
- Add URL reading keywords to RESEARCH action type detection

Weather queries now automatically include user's stored location from
the Biographer, enabling location-aware search results.
