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 value in exchange from value in
+    use and precisely captures the concept as purchasing power or command over other
+    goods. It avoids circularity by defining exchange value in terms of what can be
+    obtained through trade rather than simply referring back to exchange.
+- name: source_grounding
+  value: 5.0
+  max_value: 5.0
+  rationale: This concept is directly and explicitly discussed by Smith in Book I,
+    Chapter 4, where he makes the famous distinction between value in use and value
+    in exchange using the water-diamond paradox. The entity accurately reflects Smith's
+    original formulation without adding external interpretations.
+- name: domain_placement
+  value: 5.0
+  max_value: 5.0
+  rationale: The "Exchange" domain is perfectly appropriate since this concept is
+    fundamentally about how goods trade against each other in markets. This is a core
+    mechanism of exchange processes rather than production, distribution, or consumption.
+- name: vsm_relevance
+  value: 2.0
+  max_value: 5.0
+  rationale: This concept is quite abstract and doesn't map naturally to any specific
+    VSM system - it's more of a fundamental property that emerges from market interactions
+    rather than an operational, coordinative, regulatory, intelligence, or policy
+    function. It operates across multiple VSM levels without being specific to any.
+- name: explanatory_value
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity provides crucial explanatory power by illuminating the fundamental
+    mechanism that drives market exchange - the paradox that utility and exchange
+    value can diverge dramatically. It explains a core structural relation in how
+    markets determine relative prices and purchasing power.
