OMNIGRAPH_CLUSTER boots the container from a mounted cluster directory's
applied revision — checked first and exclusive (exit 64 when combined with
OMNIGRAPH_TARGET_URI/CONFIG/TARGET), the entrypoint-level mirror of the
server's mode-inference rule 0. The omnigraph CLI joins the image so the
day-2 loop (cluster apply/approve/status, data loads by explicit URI) runs
in-container via docker/ECS exec or railway shell — no omnigraph.yaml
required, which the cluster-local-config PR pins. entrypoint_test gains the
cluster case plus all three exclusivity refusals.
