Spectre.Governance.ChangeSet.Registry (Spectre v0.3.0)

Host-owned registry mapping inert ChangeSet operation types to reviewed code.

Registration accepts modules, never runtime data. This keeps the vocabulary extensible without a central dispatch case and without permitting a ChangeSet to choose an arbitrary handler.
