* Tracks whether notification channels have been created.

*

* Channels are **not** created in the constructor because this singleton is instantiated by Koin during

* [org.meshtastic.core.service.MeshService.onCreate] on the main thread, and channel names come from string

* resources. Instead, channels are lazily ensured before the first [dispatch] call. Note that

* [MeshNotificationManagerImpl.initChannels] already creates a superset of these channels when the orchestrator

* starts, so this lazy path is only a safety net for notifications dispatched before orchestrator initialization.

*

* The mutex is load-bearing: resolving the names suspends, so without it two concurrent [dispatch] calls could both

* pass the flag check and post before the channels exist.
