Panama learns what a server is: from a root login to running containers

A machine's role is now the interview's first question and the one answer
Panama records. Servers get the same shell minus the screen: core packages,
nvm, Bun, Claude Code and Codex (desktops get Codex too), linger, rootless
ports from 80, firewalld, the nginx-bridge network, and a nightly image
updater that replaced watchtower for cause.

server/containers/ carries junior's 23 compose services -- secrets moved to
per-machine .env files that never enter this public repo, every transformed
compose proven to render byte-identical to what is live. 'panama server'
enables, disables and relinks them; nothing here restarts a running service.
'boot --server' walks a fresh VPS from its root login to a normal install.

Five new contracts pin the secrets rule, the catalog's shape, panama-server's
behavior, the role plumbing, and the dotfile classification.
