/**
 * Watchdog for async gate jobs and (future) workforce workers.
 *
 * Two responsibilities:
 *   1. AsyncGate stale jobs — if a background job runs >3x its etaMs (or >120s
 *      with no eta), mark it failed so poll callers get a clear error.
 *   2. Workforce workers (stub) — once B1 schema ships, wired here to reclaim
 *      jobs from silently-dead workers.
 *
 * Start once at server init via startWatchdog(). The interval unref()s so it
 * won't block process exit.
