rka-oai d6350e24be Add free-form asynchronous user messages (#42354) ...

## What changed

- Add the `send_message_to_user_async` control tool for concise questions and updates during ongoing work.
- Emit messages as asynchronous agent items without ending the turn, and reject empty message text.
- Expose the tool only to root agents when the model catalog explicitly opts in, independently of `request_user_input_async`.

## Testing

- Cover catalog gating for root agents and subagents.
- Verify asynchronous item emission, tool output, empty-message validation, and continued turn execution.
