Document a phased roadmap for the single-VM deployment layer (build-off-VM,
recreate-in-place to cut downtime, change-detection + BuildKit guarantee,
image slimming + resource caps, artifact-based rollback). Scoped to deploy
orchestration; defers image-build internals to docker-build-optimization-roadmap.
Register the doc in repo-map.
