On a push to main the server-hosted runner SSHes back to the host (forced-command
key, docker bridge gateway, port 2222) and runs deploy/deploy.sh — replacing the
2-minute systemd poller. Build/publish still happens on the dev machine before push.
Drop docs/deployment-plan.md (internal planning doc, kept out of the repo) and
replace the personal lab DB IP and host names in the env/compose/deploy docs with
generic placeholders, so the repo is safe to make public later.
docker-compose.prod.yml targets the server: Postgres is never published, the
app binds to 127.0.0.1 (Caddy proxies it), and every service has a memory/CPU cap
plus no-new-privileges / cap_drop / read-only rootfs. deploy/deploy.sh rolls out
main with a host-side build (migrations run via the entrypoint). CI type-checks
and builds the frontend and byte-compiles the backend on every push to main.
