fix: improve admin privilege handling and registry cleanup

- Enhanced admin privilege checking and elevation logic in Program.cs
- Added proper error handling and user feedback for privilege requests
- Improved registry access with better null checking and resource management
- Updated registry operations to use modern C# syntax and patterns
- Modified build workflow to create single-file Windows executable

The changes ensure the application properly requests administrator privileges when needed and handles registry cleanup with improved error handling and resource management. The build process now creates a self-contained single-file executable for easier distribution.
