Publish governed meaning into dbt

dbt emits one artifact class — tables in one warehouse — and gives governed meaning nowhere to live: description is free text, meta is unvalidated, and accepted_values is a string list duplicated into every model that touches the field. This recipe closes that loop. Import the artifacts dbt already produces, govern meaning on top (descriptions, a named vocabulary behind an enum, an ontology term a human binds), then generate the contracts back as one property file per model, colocated beside each model's own .sql. One governed vocabulary generates accepted_values in every model that uses that field; a bound ontology term rides out both structurally (meta.coremodels.maps_to) and in the column description, which persist_docs carries into the warehouse column comment. Generation is deterministic, so a re-run with no meaning change is an empty diff. CoreModels returns files — your own PR flow lands them.
