merge(plane-on-kubernetes): groups 1-2 -- cluster profile, no host literals, delivery through the S3 store

Kind proofs: records 01 and 02. Task 2.6 (receiver removal) is paused while the
safety net and the decision engine come first. deployment.md conflicts resolved
in the plain-language style; corrects the RuntimeClass claim (Substrate runs
runsc inside its worker pod).
