fix(update): reap leaked serve backends during a GUI hand-off instead of dead-ending the venv sync (Windows)
...
Field incident (2026-08-20): a Windows Desktop update hand-off
(update --yes --gateway --force) left a swarm of per-profile serve
backends (mr-tester, probe-inherit, turqoise, clippy, maroon, …) holding
cryptography/_rust.pyd. Some still had a live parent (the tearing-down
Electron process, or the venv launcher->worker two-hop chain mid-exit),
so the strict orphan-only reap (_orphaned_desktop_backend_pids, which
bails the instant ANY holder has a live parent) disqualified the whole
set and the venv-holder guard dead-ended. The user saw a ~12-minute hang,
force-closed, and the half-done state stranded bot sessions.
New rung: _handoff_reapable_backend_pids reaps surviving Hermes
serve/dashboard backends from this venv — live parent or not — but ONLY
in the hand-off context the caller gates on: args.gateway AND the
update-incomplete marker present AND no live hermes.exe shim. In that
window nothing legitimate supervises or respawns a serve backend (the
Desktop tree-kills its backends and parks any relaunch behind the marker,
#50238 ), so a surviving backend is a leak, not a race. A non-backend
holder (operator REPL, stray script) still disqualifies the whole set;
psutil-unavailable returns None (keep refusing). Wired as the final rung
before the existing dead-end, after the orphan-only reap.
