The installer still needs root for apt and the firewall, but it now creates a
clupilot service account that owns the checkout and runs Docker, maps the
container user to it (HOST_UID/GID), and update.sh refuses to run as root —
root-owned files in the checkout are files the application cannot write.
The account has no password login: docker group membership is root-equivalent
on the host, so it is reachable only via sudo -u or an SSH key.

install.sh sets up a bare Debian/Ubuntu server end to end: Docker, git,
WireGuard, clone, generated secrets, stack, migrations, hub keypair, the Owner
account and a closed firewall. Re-runnable: it keeps an existing .env and never
regenerates the hub key, which would disconnect every onboarded host.
update.sh pulls and applies. Migrations run before the new containers take
traffic, the image is rebuilt only when its definition changed, and the queue
workers are restarted — they are long-running processes that otherwise keep the
old classes in memory, which cost us an hour during development.
clupilot:create-admin creates or promotes an Owner, so re-running the installer
fixes a lost role instead of failing on a taken address.
