Assembles a ready-to-write disk image via Gitea Actions. Mainline has carried sdm850-lenovo-yoga-c630.dts since 5.5 and Fedora ships it in kernel-core, so unlike aarch64-laptops/build there is no kernel or GRUB to compile — what is left is producing an image that boots on firmware which hands Linux no device tree. The build runs in an aarch64 container under qemu-user and builds filesystems from directory trees with mke2fs -d and mcopy rather than mounting loop devices, so it works on runners that will not hand out /dev/loop-control. A kernel-install hook writes the devicetree line into each BLS entry; without it the first `dnf update kernel` would produce an unbootable system.
