- Updated `InputField` to support centered alignment for better layout flexibility.
- Localized Explicit and Smart mode strings in English and French.
- Enhanced content preview logic to filter placeholder text before display.
- Added `autoUpdater` initialization checks and refactored updater setup for improved reliability.
