jschoubben 78fedabeb1 mesh-grants: own the bus's composer, so a change to who may say what rebuilds only the grants part
ADR 0593 §1: buscompose's engine moves from mesh-sdk into mesh-grants/internal/buscompose, its golden
user lists unchanged; the controller's raise and assert code is left behind, and the merged switch
test runs inside the part's whole integration test.
