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):

  source_grounding      4.36
  domain_placement      4.56
  vsm_relevance         3.31

+- name: definition_precision

+- name: domain_placement

+  max_value: 5.0
+  rationale: The concept of town-country dependency is economically relevant to Smith's

+    difficult to assess whether the thematic categorization is appropriate.
+- name: vsm_relevance
+  value: 2.0
+  max_value: 5.0
+  rationale: Town-country dependency could potentially map to multiple VSM systems
+    (S1 for operational exchanges, S4 for environmental adaptation), but without a
+    clear definition of what type of dependency is meant, it remains too vague to
+    place meaningfully within the VSM framework. The concept needs more specificity
+    to determine its systemic role.
+- name: explanatory_value
+  value: 1.0
+  max_value: 5.0
+  rationale: As currently presented, this entity provides no explanatory power since
+    it lacks both definition and context. It merely names a broad phenomenon without
+    illuminating any specific mechanisms, causal relationships, or structural dynamics
+    that would enhance understanding of Smith's economic theory.
