Summary

Adds Keenable as a web_search backend, next to Tavily, Perplexity, Exa, Brave, the OpenHack gateway and DuckDuckGo.

• _search_keenable:
  • Calls the free POST https://api.keenable.ai/v1/search/public with no key, or /v1/search with X-API-Key when KEENABLE_API_KEY is set. Sends { query, max_results } and X-Keenable-Title: OpenHack.
  • The snippet is description if present, otherwise the start of snippet, normalized by _result. Hits with no URL are dropped.
• Selection:
  • KEENABLE_API_KEY picks it after the other user keys and before the gateway, matching the "your own key wins" rule.
  • OPENHACK_SEARCH_PROVIDER=keenable picks it without a key.
  • Nothing changes for current setups.
• Tests: the keyless override path (endpoint, payload, headers, description preferred) and the keyed endpoint selection.

Disclosure: I work with the Keenable team.
