- No automatic IR1 requests; fragments arrive only when user taps load
- Bubble sends IR1 with missing indices only if partial session exists
(partial resume: only missing fragments requested, not the whole image)
- 30s timeout resets the loading spinner so user can tap retry again
- Saves LoRa airtime by never transmitting IR1 without explicit user action
- Replace 1.2s fixed retry with 10s idle debounce timer
- Timer resets on every received fragment (debounce)
- Timer also starts on IE1 envelope receipt (handles pull-only senders)
- IR1 always requests only missing indices (partial resume)
- Attempt counter no longer resets per fragment; bounded to 5 retries
- Max attempts raised to 5 (was 4)
- Remove SseClientService and ConnectionMode.sseClient
- Add ConnectionMode.tcp with MeshCoreTcpService (port 5000)
- NetworkScannerService: scan TCP port 5000 via raw Socket.connect
- mDNS service type changed to _meshcore._tcp
- connection_dialog: connect via connectTcp() instead of connectToSseServer()
- home_screen: show WiFi icon and label for TCP mode
- Bump meshcore_client to pick up TCP transport support
- Updated voice support to only include iOS, removing MacOS support.
- Added Greek (el) to the list of supported locales in LocalePreferences.
- Enhanced localization strings for Greek language.
- Modified Podfile to exclude C source files from the macOS build of codec2_flutter, as voice messages are iOS-only.
Move BLE communication layer (command queue, frame parser/builder,
protocol constants, data models) into a standalone reusable Dart package
at ../meshcore_client. App model files become thin re-export wrappers,
keeping all existing consumers working without import changes.
