- eventbus.go: Fix send-on-closed-channel panic in SubscribeGlobal by using a done channel; add recover() in fan-out goroutine; track active global subs for proper cleanup on unsubscribe - config.go: Persist JWT secret to $DATA_DIR/.jwt_secret instead of regenerating a random one on every restart (which invalidated all sessions) - handlers_ws.go: Replace time.After with time.Ticker to fix timer leak in SSE keepalive loop - handlers_jobs.go: Add recover() in fire-and-forget job goroutine; fix nil pointer deref when GetByID fails after job creation - handlers_machines.go: Add recover() in ProbeAllMachines goroutine - scheduler.go: Add recover() in scheduled job run goroutine - engine.go: Add recover() in per-machine probe goroutines
