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):

+- name: definition_precision

+  max_value: 5.0
+  rationale: The definition clearly identifies a specific social class - wage earners
+    including laborers, journeymen, and servants - and distinguishes them from other
+    economic actors. While "servants of every kind" could be more precise, the core
+    concept of wage-dependent workers is well-defined and non-circular.
+- name: source_grounding

+  rationale: This entity is directly grounded in Smith's text, particularly Book I,

+- name: domain_placement

+    relates to how the fruits of economic activity are allocated among different classes.
+- name: vsm_relevance
+  value: 4.0
+  max_value: 5.0
+  rationale: This entity maps well to S1 (primary operations) as the labouring poor
+    represent the operational workforce that performs the fundamental productive activities
+    of the economic system. They could also relate to S3 concerns regarding internal
+    regulation of working conditions and wages.
+- name: explanatory_value
+  value: 4.0
+  max_value: 5.0
+  rationale: The entity provides substantial explanatory power by identifying the
+    key social class whose welfare Smith argues determines overall societal prosperity,
+    and whose wage levels reflect the health of the economic system. It illuminates
+    the structural relationship between labor compensation and economic growth rather
