actop 1.3.2

Changed

• Docs: synced docs/DESIGN-system.md with the as-built LC-1/2/3 layering — §1
  now documents the L1→L2→L3 data-flow pillar and names analytics.py as the L2
  judgments module; §3.7 documents the SocProfile.ane_max_w reference field.
• Removed the completed docs/TODO-layering-cleanup-2026-07-02.md plan (LC-1/2/3
  all shipped in v1.2.4–v1.3.1; the as-built design now lives in DESIGN-system.md).
