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.

+- name: definition_precision

+  max_value: 5.0
+  rationale: The definition clearly distinguishes payment in kind from both pure barter
+    and monetary exchange, positioning it as a specific intermediate stage. It precisely

+    without circularity.

+- name: domain_placement
