- the customInstall macro runs `OpenSwarm.exe --prewarm` via nsExec::Exec,
which is synchronous with no upper time bound. On a clean box the silent
install launches the freshly-extracted, not-yet-signed binaries, provoking a
cold Windows Defender scan that stalls for minutes - this hung the CI
installer-verification step (no output for ~3m, then cancelled)
- both CI verification and production auto-updates run the installer with /S,
so this same stall could hang a real user's auto-update
- gate the prewarm behind ${If} ${Silent} ... ${Else}: interactive first-time
installs (where the cold-start win lands) still prewarm; silent installs skip
it and finish promptly
- verify-installer: keep the blocking spawnSync (it must wait for the registry
uninstall entry the gate checks) but add a 300s timeout so any future
synchronous stall fails the gate in minutes instead of hanging the job
