1.python3 -m huixiangdou.gradio --standalone

Start by running `python3 -m huixiangdou.gradio --standalone` and trace the `huixiangdou.gradio` entry point through the thread and asyncio startup shown in the traceback. Confirm the local-model interface starts without the “There is no current event loop” error.
