- Add elephant backend service with systemd user service
- Update walker service to depend on elephant service
- Improve waybar configuration with new modules (tray, bluetooth, battery)
- Add click handlers for network, pulseaudio, and bluetooth
- Update colors and styling for better visibility
- Include gaming-apps in laptop home configuration
