The old setup command enabled sshd before importing a key, so an aborted
run left a password-only server exposed. Skipping that machine kept the
hole Omarchy opened; close it instead by disabling sshd. Omarchy is a
desktop distro, so the console remains, and the warning explains how to
set up key-based access or deliberately re-enable password logins.
With the stakes flipped from skip to disable, "no usable key" must not
false-positive: follow an authorized_keys symlink to its key (dotfiles
setups have working key auth), and treat an unreadable file as
unverifiable rather than keyless.
Amends the unreleased 1788124236 migration in place; no released install
has run it, so every machine still gets the new behavior in one pass.
