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
+  value: 1.0
+  max_value: 5.0
+  rationale: There is no definition provided at all, making this entity completely
+    imprecise. Without any definitional content, it's impossible to assess whether
+    this captures a distinct concept or represents a vague umbrella term.
+- name: source_grounding
+  value: 1.0
+  max_value: 5.0
+  rationale: With no definition, context, or source chapter specified, there's no
+    evidence this entity is grounded in Smith's actual text. The generic title suggests
+    it may be an artificial construct rather than a concept Smith explicitly developed.
+- name: domain_placement
+  value: 2.0
+  max_value: 5.0
+  rationale: While "Colony Economic System Implementation" sounds economically relevant
+    to Smith's work on colonial trade, the unspecified domain and lack of definition
+    make it impossible to verify correct thematic placement. The title alone suggests
+    economic relevance but provides no substantive content to evaluate.
+- 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 entity might map to or whether it has any VSM relevance at all.
+    The term "implementation" could theoretically relate to S1 operations, but this
+    is pure speculation given the lack of content.
+- name: explanatory_value
+  value: 1.0
+  max_value: 5.0
+  rationale: An entity with no definition, context, or source grounding provides zero
+    explanatory power. It neither illuminates mechanisms nor structural relations,
+    functioning merely as an empty label that names nothing substantive.
