Same fix as 317a424, applied to the files an agent actually reads before
touching the host: AGENTS.md and both copies of the homelab-ssh skill.
They all claimed a headless Ubuntu server; valhalla is EndeavourOS (Arch).
Also record two things that cost time this session: there is no apt/apt-get
on the host, and ginnoir has passwordless sudo (needed for anything writing
to root-owned paths like /config/caddy/Caddyfile).
Historical records under plans/ and docs/superpowers/plans/ are left alone
on purpose — they document what was true when the work was done.
