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 identifies specific economic factors (abundant
+    cheap land, high wages, self-government, value retention) that create colonial
+    prosperity. While comprehensive, it could be slightly more precise about how these
+    factors interact mechanistically.

+  rationale: This entity is well-grounded in Smith's actual analysis in Book IV, Chapter

+  max_value: 5.0
+  rationale: '"Production" is the correct domain placement since these mechanisms

+    processes rather than exchange or distribution.'

+- name: explanatory_value
+  value: 4.0
+  max_value: 5.0
+  rationale: The entity provides genuine explanatory power by identifying the structural
