Move the catalogue tests that read mesh-catalog into go/catalogue, and lay the captured copy out once per process (issue 1379)

Imports rewritten to mesh-sdk's (beside, catalogue, overlay). Left in mesh-controller, which holds their modules: TestTheBuilderRequiresTheRegistryTheNpmSeatDelivers (foundation_manifests_test.go), TestGenesisAssignsTheBuildAgentWithNothingProvidingTheRegistry (genesis_registry_test.go, whole file), TestRouteProxyKeepsItsPublicAccountDirectory (public_issuer_test.go), TestEveryManifestInUseClaimsASeatTheMeshDefines (seats_test.go); with controller_is_a_process_test.go and genesis_image_test.go. moduleTree reads mesh-catalog only: mesh-sdk has no modules directory of its own. beside.Dir lays a repository's captured copy out once per process (a mutex and a map, os.MkdirTemp), new test TestTheCapturedCopyIsLaidOutOnce failed first (two directories). The captured copy is refreshed from the mains: mesh-catalog bb0fe93b, mesh-host cdcba9ca, only what these tests read; CAPTURED says how to move it. Unit level 1.16 s (bound 2 s).
