Debian 13 cloud image, user 'ops', build-sized resources (the control
plane builds on the target), BOX_REQUIRE_VM + BOX_AUTOSTART. cloud-init
installs docker, rig and tmux and stops: tailscale, openssh-server and
every credential are deliberately absent — rig installs and hardens those
at bootstrap time ('box shell' → 'sudo rig bootstrap workload'), and box
never sees the auth key. No agent, no agent-context file: a server, not
an agent devbox. tmux rides along because 'box tmux' is a contract every
template honors (#65), staging included.
