sparkle 2.19.0

Sparkle 2.19.0 is an open-source Windows optimization utility for Windows 10 and Windows 11. This release focuses on reversible debloat scripts, package installs, and UI fixes. It updates the app installer experience, settings interface, developer options, and package-manager checks while adding new apps and fixing performance-related UI issues. The release reflects the maturation of the Windows debloat movement, moving from one-shot scripts toward GUI-driven control panels that allow users to reduce Microsoft's preconfiguration in a reversible manner.
