First Governed Import for Neo4j

Upload the schema your Neo4j instance already describes: node labels become governed Types, properties become Elements (existence constraints → NotNull, uniqueness → Unique), and each outgoing typed relationship becomes the graph-native foreign key: a reference Element named after the relationship type. Add SHOW CONSTRAINTS rows to refine fields beyond APOC's sampled flags. A first audit is recorded so drift tracking starts on day one. No Bolt/HTTP credentials ever reach CoreModels.
