James Rich 0e47dc6717 fix(tcp): stop emitting redundant permanent disconnect from close() 
TcpRadioTransport.close() unconditionally emitted onDisconnect with
isPermanent=true. The 'closing' guard at the listener level already
suppresses the transient signal during teardown, and the explicit-
disconnect emit is owned by SharedRadioInterfaceService.stopTransportLocked.
The double-emit caused two terminal disconnect events for one user action
and prevented the auto-reconnect loop from cleanly owning its lifecycle.

:core:network

Overview

The :core:network module handles all internet-based communication, including fetching firmware metadata, device hardware definitions, and map tiles (in the fdroid flavor). It also provides the shared radio transport layer (TCPInterface, SerialTransport, BleRadioInterface).

Key Components

1. Ktor Client

The module uses Ktor as its primary HTTP client for high-performance, asynchronous networking.

2. Remote Data Sources

  • FirmwareReleaseRemoteDataSource: Fetches the latest firmware versions from GitHub or Meshtastic's metadata servers.
  • DeviceHardwareRemoteDataSource: Fetches definitions for supported Meshtastic hardware devices.

3. Shared Transports

  • BleRadioInterface: Multiplatform BLE transport powered by Kable.
  • TCPInterface: Multiplatform TCP transport.
  • SerialTransport: JVM-shared USB/Serial transport powered by jSerialComm.
  • BaseRadioTransportFactory: Common factory for instantiating the KMP transports.
