/**
 * sha256 — the content hash incremental re-indexing skips on.
 *
 * Pattern: leaf utility over `node:crypto`.
 * Role:    rag/ layer. Distinct from `lib/fnv1a` on purpose: FNV-1a identifies
 *          content for correlation inside one recording, where a collision
 *          costs a confusing trace. This one decides whether a document is
 *          RE-EMBEDDED, where a collision costs a stale answer that looks
 *          exactly like a fresh one — and it is compared across runs, machines
 *          and months rather than within a single process.
 * Emits:   N/A.
