Implement cross-platform support for NVIDIA's Parakeet TDT ASR models using sherpa-onnx runtime. Parakeet provides 50x faster transcription than Whisper with comparable accuracy. New features: - Add parakeet-tdt-0.6b-v2 (English) and v3 (25 languages) models - Create ParakeetServerManager for CLI-based transcription - Add sherpa-onnx binary download script for all platforms - Enable NVIDIA Parakeet tab in TranscriptionModelPicker UI - Support model download, delete, and selection Architecture follows existing patterns: - parakeet.js mirrors whisper.js for model management - parakeetServer.js uses sherpa-onnx-offline CLI - IPC handlers follow whisper handler patterns - useModelDownload hook extended for 'parakeet' type

Resolve conflicts in CHANGELOG.md, CLAUDE.md, electron-builder.json, and package.json by combining Parakeet/sherpa-onnx additions with Windows push-to-talk, custom dictionary, and shared download utilities from main.
