/**
 * Workflow graph store (RD §2, §4 — slice 4.0.8 presence-lease-graph).
 *
 * Safe-path, locked, atomic graph persistence. Reads fail closed on
 * malformed JSON / schema violation / cycle / unknown node id. Writes
 * use a tmp+rename primitive to guarantee no half-written graph on
 * crash. The store never inspects vendor env vars and never falls
 * back to a legacy marker when the canonical graph is unreadable —
 * canonical corruption is surfaced with `PEAKS_GRAPH_CORRUPTED`.
