watchdog: probe-resumed tick returns True — don't evaluate stale pane after resume

The tick whose probe resumed a session was continuing into stall logic with
its pre-resume pane capture; a 4h-old WAITING-UNTIL in that stale data got
the freshly-resumed adversary kill+rebooted (05:52). Treat probe-resume as
handled-this-tick; the next 30s tick sees the live session.
