// StopMonitoring looked up the "memory-monitor" task via
// GetGlobalTaskRegistry().GetTask, but CreateSingletonTask stores the task in
// the ResourceManager's registry, NOT in TaskRegistry.tasks (the R88 split).
// So GetTask always returned not-exists, Stop was never called, the monitor's
// ticker goroutine ran on past shutdown, and globalMonitoringStarted stayed
// true. StopMonitoring must actually stop the task and clear the flag.
