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: 3.0
+  max_value: 5.0
+  rationale: The definition captures a coherent concept about economic change over
+    time, but uses somewhat vague terms like "various factors" and "circumstances"
+    without specifying mechanisms. It's reasonably distinct but could be more precise
+    about what drives evolutionary processes.

+- name: vsm_relevance
+  value: 4.0
+  max_value: 5.0
+  rationale: This entity maps well to S4 (intelligence/environmental adaptation) as

+- name: explanatory_value
+  value: 2.0
+  max_value: 5.0
+  rationale: The entity names a phenomenon (systems change over time) but provides
