When the dashboard crashes mid-heartbeat, the agentRuns row is left in
status='active' forever. HeartbeatTriggerScheduler.onTimerTick treats
any active run as "still running" and skips every subsequent tick, so
agents go silent indefinitely (observed: 6+ hours). The existing
in-memory missed-heartbeat watchdog can't help — its trackedAgents map
is wiped on process restart.
SelfHealingManager.recoverStaleHeartbeatRuns now reconciles these on
startup and during periodic maintenance: terminates active runs whose
processPid does not match the current process, has no recorded pid, or
has been active for more than 6 hours.
