Nordwall v0.4.1

Fixes a WebView2 lifecycle race during display-layout updates.

• Serializes layout rebuilds and pause/resume state changes.
• Cancels an in-flight WebView2 suspension when its wallpaper window is disposed.
• Avoids accessing CoreWebView2 after the control lifetime ends.
• Keeps the existing display polling interval and adds no background work in the steady state.

Fixes #1.

Separate wallpapers

Right-click the Nordwall icon in the system tray for Pause / Resume, Open wallpapers folder, and Settings. Double-click the tray icon to open Settings. You can exit the app from the Settings window.

The Settings window has two display modes:

• Separate wallpapers — select a display in the miniature monitor diagram and choose an independent HTML, MP4, or WebM wallpaper for it. Each monitor uses its own WebView2 renderer.
• Span across displays — choose one wallpaper that occupies the union of all connected screens. It uses one WebView2 renderer, so motion and video playback remain synchronized and do not require duplicate video decoders.

If a monitor has no wallpaper assigned (or the wallpaper folder is empty), Nordwall leaves its usual Windows wallpaper visible and does not start an unnecessary renderer on that screen.

The monitor diagram shows the screen arrangement reported by Windows, including monitors to the left or above the primary screen and different resolutions. Use Arrange displays… to open Windows Display Settings and reposition displays there. Nordwall automatically detects the updated layout within about two seconds; the diagram itself does not change Windows display positions.
