debian:bookworm-slim lacks node, so actions/checkout@v4 (a JS action running dist/index.js) fails with `exec: "node": executable file not found in $PATH`. Dropping the explicit `container:` directive lets the runner use its label-default — node:20-bookworm-slim has node + git out of the box. Install step shrinks to python3 + pyyaml + openssh-client.
