UI Overhaul: The application receives a modern dark theme with a harmonious color palette, redesigned button styles, custom control templates (checkboxes, radio buttons, tooltips), and a refreshed "About" window with clickable hyperlinks to GitHub and the official website.
New Features: CHD extraction gained a user-selectable output format (Auto/CD/DVD/Hard Disk) along with an option to delete the original CHD after successful extraction.
Bug Fixes & Security: The update checker was refactored to use proper HttpRequestMessage scoping, archive extraction now validates that files cannot be written outside the target directory (path traversal fix), and cancellation handling was improved to ensure processes are fully terminated before cleanup.
