rhan-oai 7e41be641e Restrict async user messages to questions (#41365) ...

## What changed

Update the `send_user_message_async` tool guidance to reserve it for questions
that require missing information, preferences, constraints, clarification, or
approval. Ask models to keep these questions concise, understandable, and at
an appropriate level of abstraction for the user and task.
