External Tool Execution Async Responses

"""🤝 Human-in-the-Loop with OpenAI Responses API (gpt-4.1-mini)

This example mirrors the external tool execution async example but uses
OpenAIResponses with gpt-4.1-mini to validate tool-call id handling.

Run `pip install openai agno` to install dependencies.
