/**
 * Profile→REF edges as first-class graph data (#1501, reassigned from #1502).
 *
 * TS-native port of section9 `scripts/profiles/build_profile_edges.py`. Builds
 * the entity-profile → reference edge graph from `loadProfiles` (PROF-{P,O,G,F,S}
 * `corpus-refs`), reconciled against the citation graph so only edges to REFs
 * that actually exist in the corpus are kept (the source script emitted synthetic
 * `documentation/profiles/edges/` files; per the issue these are first-class
 * graph adjacency objects instead, reconcilable with the #727 graph backends).
 *
 * @source historical: profiles/build_profile_edges.py
 * @tests @test/unit/artifacts/profile-edges.test.ts
