- Blocker: arm 3s force-exit timer BEFORE awaiting cleanup, not
inside .finally(). Prevents hang if drainBrowserPool() blocks on
dead Chrome.
- Reorder cleanup: killTrackedProcesses() (sync, fast) runs first,
then async browser drain. Ffmpeg dies immediately instead of
surviving if the hard timer fires early.
- SIGKILL escalation: processTracker now SIGTERMs all tracked
processes, then SIGKILLs survivors after 500ms grace period.
- Scope pgrep to current user (pgrep -u $(id -u)) so orphan
detection doesn't touch other users' Chrome on shared machines.
- Add process.on('exit') handler for crash paths (unhandled
exceptions/rejections that bypass signal handlers).
- Document Windows no-op behavior on killProcessTree handlers.
