Keep registry key validation local to workflowdef with composition-root
injection, adapt FlatCatalog for projectworkflow, and drive the
orchestrator through LiveInstancePort views instead of projectinstance.
Seed rdev.v2.json, rd_ templates, catalog policy (order 40), squad
kind orchestration, and hard precheck requiring completed main (CDO).
Includes StageKey dynamicization from P0 and docs for P2–P4 skeleton.
