Add Keenable Search alongside the existing DuckDuckGo / Bing / Google /
Tavily / Ollama / Baidu / SearXNG providers.
- internal/infrastructure/web_search/keenable.go: KeenableProvider
implementing the WebSearchProvider interface, following the Tavily
provider pattern. Keyless by default: with no API key it calls the
public endpoint (/v1/search/public, rate-limited); a key switches to
/v1/search and lifts the cap. Base URL is hardcoded (SSRF-safe), proxy
is honored.
- Registered "keenable" in the container registry.
- Added the keenable provider type + type metadata (RequiresAPIKey=false)
and service validation (no required key, like DuckDuckGo).
- Provider-specific empty-results diagnostic (keyless rate-limit hint).
- Frontend: extend the provider union type with 'keenable'.
- Unit tests: keyless vs keyed endpoint, attribution header, maxResults
trim, result mapping, error status, name.
