James Rich 805f9a3cd2 fix(serial): refresh USB device list on Android 12+ attach and resume
Android 12+ delivers ACTION_USB_DEVICE_ATTACHED only to manifest-declared
receivers; the runtime-registered UsbBroadcastReceiver inside UsbRepository
never sees this event. Forward it explicitly from MainActivity so the
serialDevices StateFlow refreshes and the device appears in the Connect →
Serial tab without requiring the user to replug.

Also re-poll in onResume() to handle process-restart or returning from
another app while a USB device was already attached.

: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.
