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 this concept from typical local
+    town-country relationships by specifying the key differentiator - distance of
+    subsistence sources. It captures a distinct economic arrangement without being
+    circular, though it could be slightly more precise about what constitutes "very
+    distant."
+- name: source_grounding
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity is well-grounded in Smith's actual discussion in Book III,
+    Chapter 1, where he explicitly addresses how towns can obtain subsistence from
+    distant countries as an exception to the general pattern. The concept directly
+    reflects Smith's acknowledgment of variations in the typical development model.
+- name: domain_placement
+  value: 5.0
+  max_value: 5.0
+  rationale: The "Exchange" domain is perfectly appropriate since this concept fundamentally
+    concerns trade relationships and the flow of goods between geographically separated
+    economic units. It's centrally about exchange mechanisms rather than production
+    or distribution per se.
+- name: vsm_relevance
+  value: 4.0
+  max_value: 5.0
+  rationale: This entity maps well to S4 (intelligence/environmental adaptation) as
+    it represents how economic systems adapt to environmental constraints through
+    long-distance trade relationships. It also has relevance to S1 (operations) in
+    terms of how primary subsistence needs are met through alternative channels.
+- name: explanatory_value
+  value: 4.0
+  max_value: 5.0
+  rationale: The entity provides genuine explanatory power by illuminating how international
+    trade can alter natural development patterns while maintaining fundamental dependencies.
+    It helps explain variations in economic development across different historical
+    contexts and geographical situations.
