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)

  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: 4.0
+  max_value: 5.0
+  rationale: The definition is precise and captures the core concept clearly, identifying
+    three specific mechanisms (dexterity, time-saving, machinery invention) and linking
+    it to the propensity to exchange. It avoids circularity and distinguishes division
+    of labour from mere task assignment by emphasizing specialization and productivity

+- name: source_grounding
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity is directly grounded in Smith's text, as Book I, Chapter
+    2 explicitly discusses division of labour as arising from the human propensity
+    to truck, barter, and exchange. The definition accurately reflects Smith's argument
+    about how specialization emerges from exchange relationships.
+- name: domain_placement
+  value: 5.0
+  max_value: 5.0
+  rationale: The "Production" domain assignment is correct, as division of labour
+    is fundamentally about how productive processes are organized and executed. This
+    is the appropriate conceptual category for a mechanism that directly affects how
+    goods and services are created.
+- name: vsm_relevance
+  value: 4.0
+  max_value: 5.0
+  rationale: This entity maps well to S1 (primary operations) as it describes how
+    productive work is actually organized and carried out within operational units.
+    It also has some relevance to S2 (coordination) since specialized tasks require
+    coordination mechanisms to function effectively.
+- name: explanatory_value
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity provides exceptional explanatory power by illuminating the
+    fundamental mechanism through which specialization increases productivity and

+    propensities and economic efficiency rather than merely naming a surface phenomenon.
