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 distinct process of rural transformation but
+    is somewhat sprawling, combining multiple mechanisms (cultivation, infrastructure,
+    commercial wealth flows) without clearly delineating the core concept. It avoids
+    circularity but could be more focused on what specifically constitutes "improvement."
+- name: source_grounding
+  value: 4.0
+  max_value: 5.0
+  rationale: This entity appears well-grounded in Smith's actual argument from Book
+    III, Chapter 4 about how urban commerce transforms rural areas. The specific mechanisms
+    mentioned (wealthy merchants becoming country gentlemen, urban wealth funding
+    rural improvements) align with Smith's historical analysis.
+- name: domain_placement
+  value: 4.0
+  max_value: 5.0
+  rationale: Placement in "Production" domain is appropriate since this concerns the
+    enhancement of agricultural productivity and land value. The entity fundamentally
+    deals with improving the productive capacity of rural lands through better cultivation
+    and management.
+- name: vsm_relevance
+  value: 2.0
+  max_value: 5.0
+  rationale: This entity represents a high-level outcome or emergent property rather
+    than a specific systemic function, making it difficult to map to particular VSM
+    systems. It's more of a meta-result that spans multiple systems rather than belonging
+    naturally to S1-S5.
+- name: explanatory_value
+  value: 4.0
+  max_value: 5.0
+  rationale: The entity provides significant explanatory value by identifying the
+    end result of Smith's three-mechanism theory of how commerce transforms rural
+    society. It illuminates the structural relationship between urban wealth and rural
+    development, showing how commercial activity ultimately reshapes the countryside.
