The test budget: mesh-host is over 500 unit tests, so the three tests
added for ADR 0593 §6 and §7 are paid for by folding the private
network's hub refusals, its MTU cases and its no-self-peer check into
table-driven tests, each case kept.

ADR 0593 §1 and §7: compose, its bus reader and runtime reader, takein,
validate, the overlay generator, the composer's run and mesh-compose, and
the judgement of a move leave mesh-sdk for the node-engine's internal
packages, so no other module composes and a change to them rebuilds only
the node-engine. The shapes others read (the composer's request and
verdict, the overlay's names, compositions and answers) stay in mesh-sdk.
The node's grant is now a golden file of what the grants part composes,
since the composer of the bus's user list leaves mesh-sdk too.
