jschoubben 71a35a6376 MV1: move contracts and sdk under modules/, importers follow
The delivery repository's contracts and SDK live under modules/ as
mesh-delivery-contracts and mesh-delivery-sdk, their Go module paths
renamed to match the folders (the TypeScript names already did), and
every importer in mesh-delivery, mesh-catalog, mesh-host, mesh-tools
and mesh-sdk follows in the same group: a design as it should be, one
path per module, checked by the group's check building every importer.

Builds: design 47 G §427, §88

// Package catalogkey is the codec of a catalog key's parts (design 47 G §670): a fingerprint as the part of a bus
// key, and back. It imports neither mesh-sdk's views nor the bus client, so a package that only reads and writes keys
// (the builder's builds package) reaches no bus; meshcatalogclient imports it.
