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.

Viability dashboard: 6/6 PASS
  redundancy_ratio   0.0061  (max 0.10)
  coverage_ratio     0.6190  (min 0.40)
  coherence_comps    0.0000  (max 3)
  consistency_cycles 0.0000  (max 0)
  granularity_entropy 2.6748 (min 1.0)
  per_entity_mean    3.9556  (min 3.5)

Dimension breakdown (mean across 985 entities):
  definition_precision  3.62
  source_grounding      4.36
  domain_placement      4.56
  vsm_relevance         3.31

+- name: definition_precision

+  max_value: 5.0
+  rationale: The definition is overly broad and vague, essentially describing "how

+    policy implementation than a precise economic concept.
+- name: source_grounding

+  max_value: 5.0
+  rationale: The entity explicitly admits Smith does not discuss this concept in the

+    IV, Chapter 0 would also be unusual as chapters typically start with Chapter 1.
+- name: domain_placement
+  value: 3.0
+  max_value: 5.0
+  rationale: While "Regulation" is a reasonable domain for implementation processes,
+    this concept is so broad it could equally belong in institutional economics, political
+    economy, or policy studies. The domain assignment captures one aspect but doesn't
+    reflect the entity's expansive scope.
+- name: vsm_relevance
+  value: 4.0
+  max_value: 5.0
+  rationale: This entity maps well to multiple VSM systems - S1 (operational implementation),
+    S3 (internal regulation and audit of implementation), and S4 (adaptation of implementation
+    to environment). The implementation focus gives it clear VSM applicability across
+    several systems.
+- name: explanatory_value
+  value: 2.0
+  max_value: 5.0
+  rationale: The entity merely labels the general phenomenon of "putting economic
+    ideas into practice" without illuminating any specific mechanisms, structural
+    relationships, or causal processes. It adds descriptive terminology but little
+    analytical insight into how economic systems actually function.
