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.

Viability dashboard: 6/6 PASS
  redundancy_ratio   0.0061  (max 0.10)
  coverage_ratio     0.6190  (min 0.40)
  coherence_comps    0.0000  (max 3)
  consistency_cycles 0.0000  (max 0)
  granularity_entropy 2.6748 (min 1.0)
  per_entity_mean    3.9556  (min 3.5)

Dimension breakdown (mean across 985 entities):

+- name: definition_precision
+  value: 1.0
+  max_value: 5.0
+  rationale: There is no definition provided at all, making this entity completely
+    imprecise. Without any definitional content, it's impossible to assess whether
+    the concept captures something distinct or is merely a vague umbrella term.
+- name: source_grounding
+  value: 2.0
+  max_value: 5.0
+  rationale: While Smith does discuss merchant capital and employment choices in "The
+    Wealth of Nations," the lack of definition and context makes it unclear whether
+    this entity accurately reflects Smith's specific analysis. The slug suggests relevance
+    but provides no evidence of actual grounding in the source text.
+- name: domain_placement
+  value: 3.0
+  max_value: 5.0
+  rationale: The concept appears to relate to economic decision-making and capital
+    allocation, which would be appropriate for an economic domain. However, without
+    a definition or specified domain, it's difficult to assess whether the placement
+    is optimal or if it belongs in a more specific conceptual category.
+- name: vsm_relevance
+  value: 2.0
+  max_value: 5.0
+  rationale: Merchant capital employment choices could potentially map to S1 (operational
+    decisions) or S4 (strategic adaptation to market conditions), but the complete
+    lack of definition makes VSM placement speculative. The entity is too undefined
+    to establish clear VSM relevance.
+- name: explanatory_value
+  value: 1.0
+  max_value: 5.0
+  rationale: With no definition, context, or elaboration, this entity provides zero
+    explanatory power. It merely names a potential phenomenon without illuminating
+    any mechanisms, relationships, or structural insights that would enhance understanding
+    of Smith's economic theory.
