FLX-2301: the run's cast does not resolve

Family: plan/replay binding (the 2000 band)

A reference in the Simulation's closure names a document the bundle does not carry, of a kind that reference may not name, or -- for a Journey or a Detector -- one reached by a route other than moduleRefs -> Module.spec.resources. A cast that does not resolve cannot be planned, so the run stops rather than executing a subset of what the documents describe.
