Luxel 0.1.1

• A refreshed app icon.
• Installs now come from Luxel's own Flatpak repository — one command, with automatic updates through flatpak update or GNOME Software:

flatpak install --from https://luxel.hyprlab.co/flatpak/io.github.hyprlab.Luxel.flatpakref

A standalone bundle is also attached below for offline installs. Full history in CHANGELOG.md.
