🐛 Bug Fixes

Language Recognition

• Fixed language code normalization: Resolved issues with Czech (and potentially other) language recognition where language codes with underscores (cs_CZ) weren't being properly converted to the hyphen format (cs-CZ) required by Apple Vision OCR
• Fixed engine selection: Corrected issue where Tesseract engine was being selected even when disabled in preferences, causing fallback to incorrect engines with poor results
• Language identifier handling: Improved LanguageCodeMapper.standardize() to properly handle locale-based language codes

Image Preprocessing

• Enhanced text recognition accuracy: Added automatic image preprocessing with:
  • +30% contrast enhancement
  • +10% brightness adjustment
  • +10% saturation boost
• These improvements help recognize low-contrast and light-colored text more reliably
