uvloop ships no Windows wheels, so 'import uvloop' at module scope in
entrypoints/cli/serve.py killed vllm-omni serve on Windows at import
(measured in the serving e2e after the fcntl fix). _run_forever() uses
uvloop where present and asyncio.run on WindowsSelectorEventLoopPolicy
otherwise, which zmq.asyncio needs. The remaining serve-import blocker
on the Windows venv was a missing dependency, torchaudio (vLLM's own
requirement), installed into the venvs rather than patched.
