FakeRadioInterfaceService
class FakeRadioInterfaceService(val serviceScope: CoroutineScope = MainScope()) : RadioInterfaceService(source)
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 observes this flow; tests should verify that bridging behavior rather than consuming it directly from UI/feature test code (use FakeServiceRepository.connectionState instead).
