deploy.sh is the idempotent rollout path: venv + deps, launcher,
/etc/pipekit/secrets.env skeleton (mode 0600), schema init, and
auto-register of every JDBC driver shipped with jrunner. systemd
unit is a template, not auto-installed — user copies it when ready
to cut over.
`pipekit secrets {list,set,unset}` manages /etc/pipekit/secrets.env
with atomic 0600 writes so passwords don't need sudoedit. Prompted
input by default; positional value allowed for scripting.
