The fullscreen toggle had an isMaximized branch (from #872) that called unmaximize() and never setFullscreen() when the window was maximized. Phosh windows are always maximized, so the button appeared to do nothing; on Windows it only worked when the window was not maximized. Toggle fullscreen unconditionally. The maximize handler already exits fullscreen first, so the two controls stay consistent. Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
