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 captures the specific concept of foregone benefits
+    from limited market access and specialization constraints. While it could be slightly
+    more precise about the causal mechanism, it avoids circularity and distinguishes
+    this from general opportunity cost by focusing on market extent limitations.
+- name: source_grounding
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity is directly grounded in Smith's text from Book I, Chapter
+    3, with specific examples cited (the highland nailer, farmers as butchers/bakers/brewers).
+    The concept emerges naturally from Smith's discussion of how market size constraints
+    force suboptimal resource allocation.
+- name: domain_placement
+  value: 5.0
+  max_value: 5.0
+  rationale: '"General Theory" is the appropriate domain placement as this concept
+    represents a fundamental theoretical principle about market functioning and specialization
+    constraints. It''s not sector-specific but rather a core mechanism in Smith''s
+    economic framework.'
+- name: vsm_relevance
+  value: 3.0
+  max_value: 5.0
+  rationale: This entity has moderate VSM relevance, primarily relating to S4 (intelligence/adaptation)
+    as it concerns environmental constraints limiting system optimization, and S1
+    (operations) regarding production efficiency. However, it's somewhat abstract
+    and doesn't map cleanly to a single VSM system.
+- name: explanatory_value
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity provides significant explanatory power by illuminating the
+    structural relationship between market extent and economic efficiency. It reveals
+    a key mechanism in Smith's theory about how geographic and institutional constraints
+    create systematic inefficiencies through forced self-sufficiency.
