canonicalizeGraph

Produce the W3C RDFC-1.0 canonical N-Quads form + a content hash of the graph — for reproducible snapshots, deterministic diffing, and standards-compliant dataset identity. RDFC-1.0 (W3C Recommendation, 2024) assigns deterministic blank-node labels, so two graphs that are ISOMORPHIC (identical up to blank-node relabelling and triple order) produce a byte-identical canonical form and the SAME hash — a stable, content-addressable dataset identity. Returns { canonical, hash, quadCount }. Pass graph to canonicalize one named graph (e.g. "urn:vg:data"), or omit it for the whole dataset; pass includeInferred=true to fold urn:vg:inferred into the form. Read-only: never mutates the graph.
