This fork includes the following security fixes over the original:

• Batch script injection prevention - Self-update paths sanitized to strip dangerous characters
• Symlink attack protection - Temp cleanup rejects symlinks before changing permissions
• Download URL validation - Restricted to HTTPS GitHub URLs only, filenames sanitized against path traversal

• DLL hijacking prevention - VC runtime checks use absolute System32 paths
• UAC parameter injection fix - Uses subprocess.list2cmdline() for proper argument escaping

• Dead code removal - Removed unused duplicate download method
• Log memory cap - Capped at 5,000 lines to prevent unbounded memory growth
• Symlink-safe temp snapshots - Uses os.lstat() to avoid following symlinks
• Thread safety - Added threading.Lock() for shared state

• Modern UI with customtkinter (Windows 11 native dark/light theme)
• Subtle dark gray buttons with 4px corner radius
• Treeview, log, and progress bars properly themed for dark mode
• Settings and About dialogs render on top of main window
