The orphan-reap sweep (_reap_unsupervised_gateway_orphans) must not kill a
gateway that Windows Task Scheduler is actively managing. The existing
services.exe parent-chain backstop fails open: when the Task-launched conhost
bootstrap has already exited, Windows does not reparent the gateway, the
chain breaks, and the supervised gateway is treated as an orphan. The reaper
then writes the planned-stop marker, the gateway exits cleanly with code 0,
and the scheduler never restarts it (RestartCount only fires on non-zero
exit) — silently killing A2A/messaging on every desktop-app launch.
Querying the task's own state is the authoritative signal and closes the gap
without depending on process ancestry: if HermesGateway is Running, skip the
reap entirely. Uses PowerShell Get-ScheduledTask (English State enum,
locale-stable) rather than schtasks (localized output + codepage mangling).
