P1 Badge Route multi-agent through Responses API

For this model, flavor: "chat" makes the proxy's /auto path select /chat/completions (see packages/proxy/src/proxy.ts switch on modelSpec.flavor), and normal chat-completion calls are forwarded to xAI's /chat/completions. xAI's current multi-agent docs state that grok-4.20-multi-agent does not work with the OpenAI Chat Completions API and must use the xAI SDK or Responses API instead, so users who pick the newly added model through the standard chat route will get provider errors rather than a working model.
