Desktop 'lock' fix: the window no longer steals focus when a full-screen game owns the foreground at launch. Opening after an exclusive-fullscreen game (creator's THE DIVISION 2 gameplay-stream start) the window ACTIVATED by default, Windows dropped the game to the taskbar and the 1920x1040 window covered the whole work area - 'the desktop is locked and I can't reach the game with the mouse'. MainWindow ctor now sets ShowActivated = !MainViewModel.FullscreenGameRunningNow (GetForegroundFullScreenMonitorIndex() != null), so an in-game launch keeps the game focused and live; a normal launch is unchanged. New FullScreenDetectorOverride test seam (mirrors WindowEnumeratorOverride - deterministic, no real Win32 foreground state) + DesktopLockTests: game at launch -> ShowActivated=false, normal launch -> true, FullscreenGameRunningNow reflects the detector. 422 pass / 1 known env flake, 0 build warnings. (Unit: launch focus)
