release_1.9.0

• Modernized UI/UX:

  • Implemented a comprehensive global theme in App.xaml featuring a new color palette, styled buttons, and "Stat Cards" with drop shadows.
  • Redesigned the log viewer with a dark theme (#2C3E50) and Consolas font for better readability.
  • Updated the TabControl and Menu for a cleaner, borderless appearance.

• Enhanced Performance Monitoring:

  • Replaced manual file-size delta calculations with Windows Performance Counters (PhysicalDisk) to provide more accurate real-time read/write speed tracking.
  • Integrated speed monitoring into both CHD conversion and CSO extraction processes.

• New Conversion Options:

  • Added "Force createcd (CD)" and "Force createdvd (DVD)" checkboxes, allowing users to override chdman's default format detection.

• Stability & Resource Management:

  • Log Truncation: Implemented a 100,000-character limit for the log viewer to prevent UI lag during long batch operations.
  • Improved Disposal: Refactored CancellationTokenSource and PerformanceCounter handling to prevent ObjectDisposedException and memory leaks.
  • Archive Service: Updated ArchiveService to implement IDisposable for proper cleanup of system counters.

• Code Refactoring:

  • Refactored BugReportService and App.xaml.cs to ensure error reporting is initialized before other services.
  • Updated chdman logic to better handle progress reporting via standard error streams.
