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 distinguishes monopoly effects from monopoly itself,
+    focusing specifically on price consequences and efficiency impacts. It avoids
+    circularity and identifies distinct mechanisms (higher prices, reduced efficiency
+    incentives) rather than using vague terms.
+- name: source_grounding
+  value: 5.0
+  max_value: 5.0
+  rationale: This concept is directly grounded in Smith's analysis in Book IV, Chapter
+    2, where he extensively discusses how import restrictions create domestic monopolies
+    that raise prices and harm consumers. The entity accurately reflects Smith's core
+    argument about the welfare effects of trade protection.

+- name: vsm_relevance
+  value: 3.0
+  max_value: 5.0
+  rationale: This entity has moderate VSM relevance, primarily mapping to S4 (intelligence/adaptation)

+- name: explanatory_value
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity provides strong explanatory power by illuminating the causal
