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 foreign trade from inland trade
+    based on uncertainty of returns, providing a specific criterion rather than a
+    vague description. It could be slightly more precise about what constitutes "commercial
+    exchange between different countries" but the uncertainty-based distinction is
+    well-articulated.
+- name: source_grounding
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity is directly grounded in Smith's text from Book I, Chapter
+    10, where he explicitly discusses foreign trade's greater uncertainty compared
+    to inland trade and mentions specific examples like North American trade. The
+    concept and its characteristics are clearly stated in the source material.
+- name: domain_placement

+  max_value: 5.0
+  rationale: The "Exchange" domain is perfectly appropriate for foreign trade, as
+    it represents a fundamental category of commercial exchange that Smith analyzes.
+    This placement correctly captures the transactional nature of the concept within
+    Smith's economic framework.
+- name: vsm_relevance
+  value: 3.0
+  max_value: 5.0
+  rationale: Foreign trade could map to S4 (intelligence/environmental adaptation)
+    as it involves engaging with external environments and adapting to international
+    conditions, but the mapping is not particularly strong or natural. The concept
+    is more descriptive of a type of economic activity than a cybernetic function.
+- name: explanatory_value
+  value: 4.0
+  max_value: 5.0
+  rationale: This entity provides genuine explanatory value by illuminating Smith's
+    risk-return mechanism across different types of commerce and explaining profit
+    differentials between domestic and international trade. It reveals an important
+    structural relationship in Smith's analysis of capital employment rather than
+    merely naming a phenomenon.
