Breaking change: This release removes all Android/Kotlin native code and replaces the Platform Channel bridge with a pure-Dart implementation using the sherpa_onnx Flutter package.

• Pure-Dart ASR engine — AsrLib now uses sherpa_onnx directly instead of the previous Kotlin native AAR + Platform Channel bridge.
• Cross-platform support — works on Android, iOS, macOS, Windows, and Linux (all platforms supported by sherpa_onnx + record).
• Audio capture via record package — replaces Android AudioRecord.
• Model downloader in Dart — new asr_model_downloader.dart replaces the Kotlin ModelDownloader. Supports progress tracking and marker-file-based download state.
• Bundled VAD model — silero_vad.onnx is now a Flutter asset.
• android/ directory removed — no native code needed.
• Model type support — AsrConfig.modelType selects the model architecture: zipformer_ctc (default), sense_voice, or paraformer.
• New dependencies: record, path_provider, path.
• plugin: declaration removed from pubspec.yaml.

• Permission handling — AsrPermissions for microphone permission request/check (Dart layer).
• Global service registry — AsrRegistry singleton with pre-initialization support.
• UI components — VoiceRecordButton (long-press recording) and showVoiceRecordOverlay (full-screen recording dialog).
• Animation widgets — PulseAnimation, RippleAnimation, SoundLevelIndicator, WaveformDisplay.
• Text correction — GlobalTextCorrector with pinyin matching, fuzzy matching, and hotword support.
• New dependencies: permission_handler, lpinyin.
