- Filter out RDF/RDFS/OWL schema predicates (rdfs:domain, owl:inverseOf,
  etc.) from hop traversal, keeping rdf:type for data signal
- Skip edges where reranker-visible components are unlabeled IRIs, since
  the cross-encoder cannot meaningfully score raw URIs
- Add max-reranker-input safety cap (default 350) to prevent overloading
  the reranker, applied after filtering for maximum useful candidates
- Expose max-reranker-input as per-request parameter through schema,
  translator, REST API, socket client, CLI, and OpenAPI spec
- Update tests
- Update tech spec
