deploy-hub.yml builds deploy/hub/Dockerfile on the appserver runner, writes
.env from repo secrets and starts docker-compose.prod.yml (external
PostgreSQL, /data bind-mounted), then polls /health.
ci.yml used runs-on: docker, which no runner has, so jobs never started.
Build/tests and the MSI now run inside the SDK image via deploy/ci/Dockerfile,
because the host-mode runner ignores container: and has no apt-get.
