Introduces an HTTP-based MCP handler (POST /mcp) that exposes polysearch's
search capabilities to AI agents via the Model Context Protocol. Supports
tools/list, tools/call (web_search, image_search), and initialize methods.
The endpoint shares the existing SearchRunner, proxy pool, and Bearer auth,
so no additional infrastructure or credentials are needed.
