Refactor first-boot documentation and scripts to enhance Chromium startup behavior. Update start-chromium.sh to prefer Wayland for better touch support and adjust fullscreen handling for both Wayland and X11 environments. Clarify CM4 EEPROM configuration in documentation to prevent conflicts with reTerminal DM display backlight. Improve user guidance on touch interactions in Chromium.
