v1.5.37 (2026-06-12) — backlog: batched writes, dead-schema cleanup, offline evals

Fixed

• Collectors batch their writes into one transaction + executemany (was one transaction per node —
  thousands of commits on large inventories); the drift dashboard's 5 COUNT queries collapsed to one
  GROUP BY. (#1)

Changed

• Removed dead schema (edges table, nodes.parent_id); violation.status / posture_drift are
  documented as reserved-but-unwired. (#4)

Added

• Offline regression evals (no live-lab env var needed) pinning the v1.5.36 compliance-correctness fixes
  and the approval-gate truth table. (#5)
