Inferray: fast in-memory RDF inference

Summary: Inferray delivers fast in-memory RDFS, ρ_df, and RDFS-Plus inference via vertically partitioned RDF storage, sequential sort-merge joins, optimized 64-bit integer sorting, and dedicated closure storage. It substantially outperforms prior systems, especially for transitive closure. (summarized by gpt-5.6-luna on Jul 24 2026)
