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 clearly identifies a specific developmental pattern where
+    coastal regions develop economically before inland areas due to water transport
+    advantages. It avoids circularity and captures a distinct geographic-economic
+    phenomenon rather than a vague concept.
+- name: source_grounding
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity is directly grounded in Smith's explicit argument in Book
+    I, Chapter 3, where he discusses how improvements in arts and industry begin where
+    water-carriage opens markets. The examples of North American colonies and Mediterranean
+    civilizations are specifically mentioned by Smith.
+- name: domain_placement
+  value: 4.0
+  max_value: 5.0
+  rationale: The "Production" domain is appropriate since this concept relates to
+    how productive activities and industrial development emerge geographically. However,
+    it could arguably also fit in a "Trade" or "Geography" domain given its emphasis
+    on market access and spatial development patterns.
+- name: vsm_relevance
+  value: 3.0
+  max_value: 5.0
+  rationale: This entity has moderate VSM relevance, potentially mapping to S4 (intelligence/environmental
+    adaptation) as it describes how economic systems adapt to environmental advantages
+    like coastal access. However, it's more of a developmental pattern than a functional
+    system component.
+- name: explanatory_value
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity provides strong explanatory power by illuminating the mechanism
+    behind geographic patterns of economic development - specifically how transportation
+    costs and market access drive the spatial sequence of industrialization. It explains
+    why certain regions develop first rather than merely describing that they do.
