* A test double for [RadioInterfaceService] that provides an in-memory implementation.

*

* The [connectionState] here mirrors the transport-level semantics of the real implementation. In production, only

* [MeshConnectionManager][org.meshtastic.core.repository.MeshConnectionManager] observes this flow; tests should verify

* that bridging behavior rather than consuming it directly from UI/feature test code (use

* [FakeServiceRepository.connectionState] instead).
