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: 4.0
+  max_value: 5.0
+  rationale: The definition is precise and non-circular, clearly distinguishing the
+    productive class by their specific economic function of generating surplus value
+    beyond their own consumption. It captures a distinct concept with clear boundaries
+    based on the ability to reproduce and increase societal wealth.
+- name: source_grounding
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity is directly grounded in Smith's text from Book IV, Chapter
+    9, where he explicitly discusses the physiocratic classification of society into
+    productive and unproductive classes. The definition accurately reflects Smith's
+    presentation of how agricultural systems view cultivators as uniquely productive.
+- name: domain_placement
+  value: 5.0
+  max_value: 5.0
+  rationale: The "Production" domain assignment is perfectly appropriate since this
+    concept fundamentally concerns the classification of economic actors based on
+    their productive capacity. This is a core production theory concept that distinguishes
+    between different types of economic activity.
+- name: vsm_relevance
+  value: 3.0
+  max_value: 5.0
+  rationale: This entity maps most naturally to S1 (primary operations) as it represents
+    the fundamental value-creating activities of an economic system. However, it's
+    somewhat abstract as a classification concept rather than a concrete operational
+    mechanism, making the VSM mapping less direct.
+- name: explanatory_value
+  value: 4.0
+  max_value: 5.0
+  rationale: The entity provides significant explanatory value by illuminating Smith's
+    analysis of different economic theories about what constitutes truly productive
+    economic activity. It reveals the structural relationship between agricultural
+    surplus generation and national wealth accumulation in physiocratic thinking.
