test_e2e_serve_text.py no longer imports tests.helpers.runtime (it pulls
the media/diffusion test helpers and therefore diffusers, absent from the
Windows venv); a small Popen launcher with a psutil process-tree kill
replaces OmniServer for this one test.
vllm-omni serve died at import on Windows: entrypoints/cli imports
benchmarks.patch -> benchmarks/omniinteract.py, which did 'import fcntl'
at module scope. Its output lock is rebuilt on the fork's
_filelock_compat primitive (fcntl on POSIX, msvcrt on Windows).
engine/stage_phase_lock.py (parallel_stage_init's SH/EX device locks)
gets the same treatment: fcntl optional, modes spelled locally, and on
Windows both modes map to the exclusive byte lock -- more serialising,
never less safe. Measured: the serving e2e's server exited with
ModuleNotFoundError: No module named 'fcntl' on both Windows venvs.

pytest-asyncio builds its loops from the current policy; on win32 that is
the Proactor loop, which zmq.asyncio cannot use, so the engine/serving e2e
hung at the first async socket (30 min, no output, GPU idle) while the
accept CLI -- which installs WindowsSelectorEventLoopPolicy itself --
passed on the same venv. The conftest now installs the same policy and
provides it as pytest-asyncio's event_loop_policy fixture.

Drives `vllm-omni serve <model> --omni` as a subprocess through the
online-serving launcher and checks /health, /v1/models, non-streaming
and streaming chat completions, and that a client disconnect mid-stream
leaves the server answering. Sets VLLM_USE_FLASHINFER_SAMPLER=0 like
LocalTextEngine does: the flashinfer sampler JITs with nvcc at runtime,
which a venv without a CUDA toolkit does not have (measured: the WSL
reference venv died in profile_run with 'Could not find nvcc').

Verbatim copy of the edge/omni-edge working tree (tracked diffs + untracked
edge/local, tests/edge/local, docs/edge, pipeline files). Taken so that
vLLM-Omni v0.29.0rc1 can be merged on a branch without touching the
user's working tree. logs_edge/ and benchmark .npy outputs excluded.
