Push-to-talk voice messaging using the Codec2 ultra-low-bitrate speech codec, transmitted as V: prefixed packets over the existing MeshCore LoRa mesh pipeline. Voice recording UI (long-press send button or + menu) is gated behind Platform.isIOS || Platform.isMacOS since the `record` package only supports microphone capture on those platforms in this build. Key changes: - VoiceRecorderService: streams 8kHz mono PCM chunks via `record` package - VoicePlayerService: decodes Codec2 bytes to WAV and plays via audioplayers - VoiceCodecService: async Codec2 encode/decode in background isolates - VoiceProvider: reassembles multi-packet sessions, drives playback - VoiceMessageBubble: shows packet progress, play/stop controls - MessagesProvider: detects V: prefix, routes to VoiceProvider - MessagesTab: PTT long-press gesture + recording indicator (iOS/macOS) - Message model: isVoice + voiceId fields for session tracking - Auto-selects codec mode from radio bandwidth (700C/1200/1300 bps) - codec2_flutter + meshcore_client switched from path to git deps
