chakana_wiring.py — Canonical 21-edge wiring for CHAKANA v3 spine (9 nodes).

Maxwell rigidity criterion: M = b - 3j + 6 = 0
  j = 9 nodes, b = 21 edges → M = 21 - 27 + 6 = 0  ✓

Edges are DIRECTED (→) because AMARU is a directional cognitive pipeline.
The Maxwell criterion is classically undirected; see WIRING_RATIONALE.md for
the caveat and our mitigating convention.
