選択肢

1. It replies with an InputRequiredResult carrying an elicitation/create request, and the client retries the original request with the collected inputResponses.
2. It waits on the same request until the client volunteers the value.
3. It opens a second stream and sends an elicitation/create request on it, waiting for the client's response before it resumes the original request.
4. It returns a JSON-RPC error with code -32602 so the client knows to ask the user.
