Enhance the NETWORK-BOOT-LXC.md documentation with detailed steps for testing network boot functionality, including prerequisites, expected outcomes, and quick testing methods. Introduce a new section on monitoring network boot status on the LXC, outlining commands to check DHCP leases, dnsmasq status, and registered devices. Update the initramfs scripts to support a rescue mode for devices stuck in network-only boot, allowing users to change boot order settings. Include a new rescue script for eMMC management in the build process.
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.
