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)

+- name: definition_precision
+  value: 4.0
+  max_value: 5.0
+  rationale: The definition clearly describes a specific settlement pattern with identifiable
+    characteristics - skilled craftsmen clustering near agricultural areas due to
+    mutual assistance needs and customer proximity. It avoids circularity and captures
+    a distinct socio-economic phenomenon rather than a vague concept.
+- name: source_grounding
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity directly reflects Smith's discussion in Book III, Chapter
+    1 about how artificers naturally settle near agricultural communities and form
+    the basis of market towns. The concept of mutual dependence and service requirements
+    driving settlement patterns is explicitly present in Smith's analysis of urban
+    formation.
+- name: domain_placement
+  value: 4.0
+  max_value: 5.0
+  rationale: The "Exchange" domain is appropriate since this settlement pattern facilitates
+    trade between craftsmen and agricultural producers, and among craftsmen themselves.
+    However, it could also reasonably fit in a "Social Organization" or "Urban Development"
+    domain if those existed.
+- name: vsm_relevance
+  value: 3.0
+  max_value: 5.0
+  rationale: This entity has moderate VSM relevance as it represents an emergent organizational
+    structure that enables coordination (S2) and operational efficiency (S1) through
+    spatial proximity. However, it's more of a structural precondition for viable
+    systems rather than a direct VSM component.
+- name: explanatory_value
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity provides excellent explanatory power by illuminating the
+    fundamental mechanism of how division of labor and market towns emerge from basic
+    economic needs. It reveals the structural logic behind urban formation and the
+    spatial organization of economic activity.
