ModuleTrees answers each module directory's git tree, its manifest and lock digests, and the git objects of the paths its
artifacts name; it no longer computes delivery.NamedTree or reads the mesh packages out of go.sum.

The runner, the toolchain guard, the fetch, the parsers, buildcpu, the conformance kit and mesh-pack move from mesh-sdk's
buildstep into modules/mesh-build-go/buildstep (own go.mod). mesh-build-go, mesh-build-node and mesh-build-image require it
by a same-repository replace; what the delivery parts read (the failure contract, the fetch request, the stale sweep, the
module tree shape, NewID, CapacitySetting) stays imported from mesh-sdk as sdkstep.
