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.

+- name: definition_precision
+  value: 4.0
+  max_value: 5.0
+  rationale: The definition clearly identifies specific components (implements, animals,

+    of productive capital in agriculture.
+- name: source_grounding

+  rationale: This entity is directly grounded in Smith's discussion in Book I, Chapter

+    from Smith's analysis rather than being imposed.

+- name: vsm_relevance
