Subject: [PATCH] desktop: patch AppImage for Wayland compatibility

The linuxdeploy-plugin-gtk hook forces GDK_BACKEND=x11, which
prevents GTK initialization on Wayland-only systems. The bundled
libgdk-3.so already has Wayland support built in.

Add a post-build step that extracts the AppImage, comments out the
GDK_BACKEND=x11 line, and repackages with appimagetool.
