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

+- name: source_grounding

+  rationale: With no source chapter specified and no definition or context provided,

+    be anachronistic for Smith's era.
+- name: domain_placement
+  value: 1.0
+  max_value: 5.0
+  rationale: The domain is listed as "unspecified," providing no basis for evaluating

+    entity is supposed to represent, domain placement cannot be assessed.
+- name: vsm_relevance
+  value: 1.0
+  max_value: 5.0
+  rationale: Without any definition or context, it's impossible to determine which
+    VSM system this might relate to or whether it has any VSM relevance at all. The
+    entity provides no information to enable VSM mapping.
+- name: explanatory_value
+  value: 1.0
+  max_value: 5.0
+  rationale: An entity with no definition, context, or source grounding cannot provide
