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 this system from market-based relationships
+    by focusing on direct subsistence provision and obligation structures. It precisely
+    captures the mechanism of surplus consumption through maintaining dependents rather
+    than through exchange.
+- name: source_grounding
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity is directly grounded in Smith's analysis in Book III, Chapter
+    4, where he explicitly describes how great proprietors maintained retainers and
+    dependents because they lacked commercial outlets for their surplus produce. The
+    concept faithfully represents Smith's historical account of pre-commercial social
+    organization.
+- name: domain_placement
+  value: 4.0
+  max_value: 5.0
+  rationale: Placement in "Distribution" is appropriate since this system fundamentally
+    concerns how agricultural surplus is allocated between landowners and their dependents.
+    While it has governance aspects, the core mechanism is distributive rather than
+    purely political.
+- name: vsm_relevance
+  value: 3.0
+  max_value: 5.0
+  rationale: This maps reasonably well to S1 (primary operations) as a basic social-economic
+    operating system, and has S5 (identity/policy) elements in terms of social structure
+    and power relations. However, it represents a complete alternative to market systems
+    rather than fitting neatly within VSM categories designed for organizational analysis.
+- name: explanatory_value
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity provides crucial explanatory power for understanding Smith's
+    historical analysis of how societies transition from feudal to commercial systems.
+    It illuminates the structural mechanism that created feudal power relations and
+    explains why commercial development dissolved these dependencies.
