test(hermes_cli): harden concurrent-gate fixture against partial-import race (#42626)
The autouse _suppress_concurrent_hermes_gate fixture did
monkeypatch.setattr(main, '_detect_concurrent_hermes_instances', ...) with
no raising=False. Its try/except guards the import but not the setattr, so
under pytest's per-test spawn isolation a transiently partial hermes_cli.main
module (one a concurrent worker is mid-importing) made setattr raise
AttributeError and errored unrelated tests in the slice.

Add raising=False so a transiently-absent attribute is a no-op default rather
than a hard error. The attribute always exists once main.py finishes
importing; the real-function opt-out (@pytest.mark.real_concurrent_gate) is
unaffected.

those tasks into ``skipped_nonspawnable`` instead of spawning, which

The Windows update path now refuses to proceed when another

flag the running agent as a concurrent instance and abort every
``cmd_update`` test. Tests that want to exercise the gate explicitly
re-patch ``_detect_concurrent_hermes_instances`` with their own
return value — autouse here gives a clean default without touching
the rest of the suite.
