The run rebuilds the module runtimes its beds stock

A per-module bed stocks mesh-runtime-<module>:development from the workstation's
image store, built by hand by a script the suite never called; six were two weeks
older than the manifests they served. For the beds named, every runtime their
scenarios stock is compared against the module's source and the tool runtime and
SDK it is built on, and rebuilt where older, missing or uncommitted; a failed
build stops the suite (novox/hq 04-ISSUES/075).
