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

+  max_value: 5.0
+  rationale: The definition clearly identifies specific non-economic attractions (beauty,

+- name: vsm_relevance

+- name: explanatory_value

+  rationale: The entity provides genuine explanatory power by identifying non-economic
