<message>Add a cleanup function to handle cancellation of the xz compression process in the build-cloudinit-image.sh script. This enhancement allows for a more robust response to cancellation requests, ensuring that resources are properly released and status messages are updated accordingly. The script now traps termination signals and cleans up temporary files, improving the overall reliability of the cloud-init image building workflow.
reTerminal DM4 eMMC provisioning
Automatically deploy or backup the CM4 eMMC when the reTerminal is connected in USB boot mode or when it boots over the network. Uses cloud-init for first-boot configuration.

Quick start
- Read docs/EMMC-PROVISIONING-GUIDE.md for setup and usage.
- Proxmox: Use scripts/deploy-to-proxmox.sh to deploy to a Proxmox host; see docs/PROXMOX-LXC-DEPLOYMENT.md.
- Manual host: Copy scripts from
host/to the host and install the udev rule (see the guide). - 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.
