Web search API

Search the web and get ranked results (title, URL, snippet) for a query — the core 'find information' primitive every agent needs. Answers 'search the web for X', 'find pages about Y', 'what does the web say about Z', 'look up W online'. Backed by SearXNG or Brave when configured, with a keyless fallback so it always responds.
