v1.0.1 Feature Update and Polish

Full Changelog:

[New Features]
- Added Native Translation Mode:
  - Whisper model now fully supports Translating any language to English
  - Added 'task' and 'language' parameters to Transcriber core
- Dual Hotkey Support:
  - Added separate Global Hotkeys for Transcribe (default F8) and Translate (default F10)
  - Both hotkeys are fully customizable in Settings
  - Engine dynamically switches modes based on which key is pressed

[UI/UX Improvements]
- Settings Window:
  - Widened Hotkey Input fields (240px) to accommodate long combinations
  - Added Pretty-Printing for hotkey sequences (e.g. 'ctrl+f9' display as 'Ctrl + F9')
  - Replaced Country Code dropdown with Full Language Names (99+ languages)
  - Made Language Dropdown scrollable (max height 300px) to prevent screen overflow
  - Removed redundant 'Task' selector (replaced by dedicated hotkeys)
- System Tray:
  - Tooltip now displays both Transcribe and Translate hotkeys
  - Tooltip hotkeys are formatted readably

[Core & Performance]
- Bootstrapper:
  - Implemented Smart Incremental Sync
  - Now checks filesize and content hash before copying files
  - Drastically reduces startup time for subsequent runs
  - Preserves user settings.json during updates
- Backend:
  - Fixed HotkeyManager to support dynamic configuration keys
  - Fixed Language Lock: selecting a language now correctly forces the model to use it
  - Refactored bridge/main connection for language list handling
