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
+  value: 4.0
+  max_value: 5.0
+  rationale: The definition clearly articulates the specific mercantilist mechanism
+    involving precious metals accumulation through trade surpluses and government
+    intervention. It avoids circularity and identifies distinct policy tools (tariffs,
+    bounties, monopolies) that constitute the mechanism.

+  max_value: 5.0
+  rationale: This entity is directly grounded in Smith's extensive critique of mercantilism

+    policies aim to achieve national enrichment through the described mechanisms.

+- name: vsm_relevance

+  max_value: 5.0
+  rationale: This entity maps primarily to S4 (intelligence/environmental adaptation)

+- name: explanatory_value

+  max_value: 5.0
+  rationale: This entity provides excellent explanatory power by identifying the core
