- scripts/package.sh: the shared script, identical to templates/package.sh.
- .github/workflows/package.yml: the packaging action of the device repository,
with the firmware checkout as the value to replace.
- board.toml: [package] unixnu, [package.defconfig], and the commented shapes of
firmware preflight, [bootimg] dtb and an os_override with its remove list.
- AGENTS.md, README.md: the one-command build replaces the per-step command list.
