AppTabbedManager.initialize() re-runs on every /app navigation (its
'initialized' flag is never set true), and setupURLMonitoring() /
setupTaskEventListeners() add window listeners (popstate, taskCreated/
Completed/Updated) unguarded — so each app-detail visit stacked another
listener set. Bind them once via a _listenersWired flag (mirrors the
existing _watchdogStarted guard). Pre-existing leak surfaced by the
feature-migration review.
