A bed that assigns mosquitto and asserts the run-once step seeded dynsec
before the broker: the bootstrap ran to completion (not left running), the
seed is on disk owned by the broker's uid, the broker is up and stable
(it crash-loops against an unseeded store, so a stable broker is the proof),
and the node reached current. On top, the seeded admin authenticates over
MQTT and the provisioner grants a scoped client a consumer connects with.
build-module-runtime.sh gains a mosquitto arm (install mosquitto_ctrl from
the mosquitto package — it is not in mosquitto-clients on bookworm, and a
musl binary from eclipse-mosquitto would not load) and compiles the module's
bootstrap/index.ts entrypoint.
