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 it impossible to assess
+    the precision or distinctness of the concept. Without a definition, this entity
+    lacks the basic conceptual clarity needed for meaningful analysis.
+- name: source_grounding
+  value: 2.0
+  max_value: 5.0
+  rationale: While Smith does discuss tobacco trade and monopolies in "The Wealth
+    of Nations," the lack of chapter specification and context makes it unclear whether
+    this specific framing as "monopoly of tobacco trade" accurately reflects Smith's
+    treatment. The entity appears to reference legitimate source material but lacks
+    proper grounding documentation.
+- name: domain_placement
+  value: 3.0
+  max_value: 5.0
+  rationale: The concept of tobacco trade monopolies would naturally fit within Smith's
+    discussions of mercantilism, colonial trade restrictions, and market distortions.
+    However, without domain specification or context, it's difficult to confirm appropriate
+    categorical placement within the broader economic framework.
+- name: vsm_relevance
+  value: 2.0
+  max_value: 5.0
+  rationale: A tobacco trade monopoly could potentially map to S1 (as a specific operational
+    system) or S3 (as a regulatory mechanism), but the complete lack of definition
+    and context makes VSM placement speculative. The entity is too underdeveloped
+    to establish clear systemic relevance.
+- name: explanatory_value
+  value: 1.0
+  max_value: 5.0
+  rationale: Without definition, context, or source grounding, this entity provides
+    no explanatory power regarding economic mechanisms or structural relations. It
+    appears to merely name a phenomenon without illuminating how it functions within
+    Smith's analytical framework.
