nearxos df180120aa Update TODO and README files to reflect enhancements in kiosk functionality and provisioning scripts</message> 
<message>Revise the TODO list to mark completed tasks related to taskbar icon changes, dark theme fixes, and script optimizations for kiosk mode. Update the README files to clarify the structure of the cloud-init fileserver, including new touch-friendly Chromium flags and the addition of a no-select extension for kiosk use. Remove the obsolete touchscreen quirks file to streamline the project. These changes improve documentation clarity and reflect the latest enhancements in the provisioning process.

reTerminal DM4 eMMC provisioning

Revisions are tracked project-wide; see repo root README.md and scripts/bump-revision.sh.

Quick start

  1. Read docs/EMMC-PROVISIONING-GUIDE.md for setup and usage.
  2. Proxmox: Use scripts/deploy-to-proxmox.sh to deploy to a Proxmox host; see docs/PROXMOX-LXC-DEPLOYMENT.md.
  3. Manual host: Copy scripts from host/ to the host and install the udev rule (see the guide).
  4. Put golden.img in /var/lib/cm4-provisioning/ (or your configured path). When a device is detected (USB or network), the dashboard asks Backup or Deploy.
