DesktopUpdaterController class

Coordinates update checks, downloads, and install handoff for UI code.

The controller owns the high-level UpdateState used by the ready-made widgets and by custom Flutter UI. Automatic startup checks run quietly and report failures through state; explicit calls such as checkVersion keep throwing so apps can handle user-triggered failures directly.
