/**
 * Smoke test: ADR-130 Phase 4 — Plugin adapter contract
 *
 * Acceptance criteria:
 *  1. GraphEdgesSource reads edges from graph_edges correctly
 *  2. KnowledgeGraphAdapter can be created with GraphEdgesSource (autoRegister path)
 *  3. Exported SparseMatrix has correct structure
 *  4. ruflo-plugin-creator SKILL.md mentions graph_adapter stub
 *
 * Usage: node scripts/smoke-graph-plugin-adapter.mjs
