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 is quite precise, clearly specifying the ability of dealers
+    to change trades without restriction and linking this to price gravitational effects.
+    It captures a distinct economic condition rather than being vague or circular.
+- name: source_grounding

+  max_value: 5.0
+  rationale: This entity is directly grounded in Smith's text from Book I, Chapter

+- name: domain_placement

+  max_value: 5.0
+  rationale: The "Regulation" domain assignment is exactly correct, as this concept

+- name: vsm_relevance
+  value: 3.0
+  max_value: 5.0
+  rationale: This entity has moderate VSM relevance, primarily mapping to S2 (coordination)
+    as it describes conditions that prevent market oscillations and distortions. However,

+    mechanism.
+- name: explanatory_value

+  rationale: This entity provides excellent explanatory value by identifying the foundational
