feat(example): add per-entity LLM evaluations for 985 WoN entities (S3.3)

Batch evaluation of all 988 entities via OpenRouter. 984 succeeded on
first pass; 3 failed (network errors). eval-summary --update-metrics
written with per_entity_mean=3.9556.

Viability dashboard: 6/6 PASS
  redundancy_ratio   0.0061  (max 0.10)

+- name: definition_precision

+  max_value: 5.0
+  rationale: The definition is precise and captures a distinct concept - a specific
+    manufacturing trade that serves as Smith's key example of division of labor. It

+    being circular.
