- Remove exactly the codeman-node-modules/codeman-dist volumes by Compose
label after a plain `down`, instead of `down --volumes` (which also takes
any volume an override file declares while the message named two).
`down --volumes` remains only as a warned fallback when the project name
cannot be resolved.
- Report a failing first `docker compose config --format json` call with a
clear error instead of exiting silently under `set -e`.
- Filter empty label lines in the collision guard so an unlabelled container
cannot hide a real collision; name the moved-checkout exit in its error.
- Comments no longer cite a guard or incident in Start-Codeman.sh that does
not exist; the README states the real gap (a Node base-image bump leaves
codeman-node-modules stale because the lockfile did not move).
- docs: Update-Codeman.sh in the docker-self-update.md short-version table
and a mention in docker-compose.md; "Major updates" moved under "Updating"
in docker/README.md.
- test: smoke test covers the new sequence, the config failure and the
empty-line case; quiet stdio; @fileoverview names the fourth concern.
