- Add backend API routes for companies.sh catalog with pagination and search - Wire frontend API client with browse mode endpoints (search, list agents) - Build Agent Import modal with tabbed interface (URL input + browse mode) - Add browse mode styling with search results grid and agent cards - Include UI and route test coverage for browse flow - Update in-UI help text with browse mode usage instructions
