Declare the seat verbs the Go package calls on a module's behalf (A-357)

Every module built against the SDK reads its catalog half through mesh-catalog's registrations, revision and entry and
mesh-delivery's source; naming them in the Go package's calls lets the indexer order such a module after the running
versions that serve its start.

Builds: design 47 G lead answer A-357 (the SDK half), §47 kind 6
