NotImplementedError with add_signal_handler on Windows Platform

[Ethycs]

On a Windows setup, I've encountered a NotImplementedError in the asyncio.events.add_signal_handler method. Here's the traceback:

Traceback (most recent call last):
  File "F:\OneDrive\jupyter\remote_llm\mock_llm.py", line 30, in <module>
    asyncio.run(main())

    return loop.run_until_complete(main)

    with graceful_exit([server]):

    return next(self.gen)

    loop.add_signal_handler(sig_num, _exit_handler, sig_num, servers, flag)
  File "C:\miniconda3\envs\remote_llm\lib\asyncio\events.py", line 553, in add_signal_handler
    raise NotImplementedError
NotImplementedError

It seems the add_signal_handler method is not supported on Windows platforms, leading to this error.
