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

  domain_placement      4.56
  vsm_relevance         3.31

+- name: definition_precision

+  max_value: 5.0
+  rationale: The definition is overly broad and circular, essentially defining economic
+    system analysis as "examining economic arrangements to understand how they function."
+    It lacks specificity about what distinguishes this from general economic inquiry
+    and reads more like a generic description than a precise conceptual definition.
+- name: source_grounding

+  max_value: 5.0
+  rationale: While Smith does analyze different economic systems in Book IV, the entity
+    appears to abstract this into a meta-concept that Smith himself doesn't explicitly

+- name: vsm_relevance
+  value: 2.0
+  max_value: 5.0
+  rationale: This entity is too abstract and meta-analytical to map meaningfully to

+    a functional component of an economic system, making it largely VSM-neutral but
+    not in a useful way.
+- name: explanatory_value

+  max_value: 5.0
+  rationale: The entity adds little explanatory power beyond naming what economists
+    generally do when studying systems. It doesn't illuminate specific mechanisms,

+    analytical concepts Smith actually discusses.
