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.

+- name: definition_precision
+  value: 4.0
+  max_value: 5.0
+  rationale: The definition clearly distinguishes between different transportation
+    modes and their cost implications, with specific focus on water vs. land carriage.
+    It avoids circularity and captures a distinct economic concept that directly affects
+    market dynamics.
+- name: source_grounding
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity is directly grounded in Smith's detailed calculations comparing
+    the resource requirements of different transportation methods (100 men + 400 horses
+    for land vs. 6-8 men + ship for water). The concept emerges naturally from Smith's
+    analysis rather than being imposed from external frameworks.
+- name: domain_placement
+  value: 5.0
+  max_value: 5.0
+  rationale: The "Exchange" domain is perfectly appropriate since transportation cost
+    differentials directly determine which goods can be profitably traded and over
+    what distances. This is fundamentally about the mechanics and feasibility of market
+    exchange.
+- name: vsm_relevance
+  value: 3.0
+  max_value: 5.0
+  rationale: This entity has some relevance to S1 (operational constraints on primary
+    activities) and S4 (environmental factors affecting system adaptation), but it's
+    more of an environmental constraint than a core VSM system component. It influences
+    system behavior without being a control mechanism itself.
+- name: explanatory_value
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity provides excellent explanatory power by illuminating the
+    fundamental mechanism that determines market extent and specialization patterns.
+    It explains why certain trade relationships exist while others don't, making it
+    a key structural determinant rather than just a surface observation.
