alishobeiri-oai b979d4f1f0 Add a feature flag for asynchronous user messages (#45124) ...

## What changed

Add the disabled-by-default `send_message_to_user_async` feature flag so root agents can use the tool without model catalog support. Preserve catalog-based opt-in and keep the tool unavailable to subagents. Register the flag as under development and expose it in the configuration schema.

## Testing

Extend integration tests to cover feature and catalog opt-ins, deduplication when both are enabled, subagent exclusion, and the retired `send_async_message` flag. Check that either opt-in allows messages to be emitted without ending the turn.
