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 distinguishes economic spatial inequality as persistent
+    regional differences based on geography and market access, avoiding circularity.
+    It could be slightly more precise about the mechanisms that create persistence,
+    but overall captures a distinct concept.
+- name: source_grounding

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

+    observations about geographical determinants of economic development.

+- name: explanatory_value
+  value: 4.0
+  max_value: 5.0
+  rationale: The entity provides genuine explanatory power by identifying geography
