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 commercial society from subsistence-based
+    organization through the key criterion of widespread exchange and trade. It avoids
+    circularity by grounding the concept in observable social practices rather than
+    abstract economic theory.
+- name: source_grounding
