+/**
+ * Works around a well-known Android bug where the [NotificationListenerService] is not
+ * automatically re-bound after a device reboot. When this happens the app silently stops
+ * receiving media session updates until the notification access permission is manually
+ * toggled off and on again (a frequent problem on Android TV).
+ *
+ * On boot we force the system to rebind the listener:
+ *  1. Disabling then re-enabling the service component. This is the programmatic equivalent
+ *     of the manual permission toggle and reliably triggers a rebind, including on the
+ *     devices where the official API alone is not enough. It does not affect the granted
+ *     notification-access permission (that grant is stored separately, by component name).
+ *  2. [NotificationListenerService.requestRebind] — the official API (API 24+) as a final nudge.
