nearxos f42700848a Enhance first-boot script to support dynamic dark theme selection and taskbar configuration</message> 
<message>Update the first-boot.sh script to dynamically select a dark theme based on the availability of PiXnoir or Adwaita-dark. Implement functionality to deploy a dark-themed taskbar configuration for wf-panel-pi, ensuring a cohesive user interface. Additionally, improve logging for theme settings and taskbar installations, enhancing the overall user experience during the first boot process.
