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 is clear and specific, identifying a distinct economic
+    condition where labor demand exceeds supply in particular localities, leading
+    to wage increases. It avoids circularity and captures a precise market phenomenon
+    rather than a vague concept.
+- name: source_grounding
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity is directly grounded in Smith's discussion of settlement
+    laws and their effects on labor mobility in Book I, Chapter 10. The concept of
+    "scarcity of hands" and its relationship to wage disparities is explicitly addressed
+    in the source text.
+- name: domain_placement
+  value: 5.0
+  max_value: 5.0
+  rationale: The placement in "Distribution" is correct, as this concept directly
+    concerns how wages (a form of income distribution) are determined by labor supply
+    and demand dynamics. It fits naturally within distributional analysis rather than
+    production or exchange domains.
+- name: vsm_relevance
+  value: 3.0
+  max_value: 5.0
+  rationale: This entity has moderate VSM relevance, primarily mapping to S1 (operational
+    labor allocation) and S2 (coordination failures between regions). However, it
+    represents more of a market condition than a clear systemic function, making the
+    VSM mapping somewhat indirect.
+- name: explanatory_value
+  value: 4.0
+  max_value: 5.0
+  rationale: The entity provides strong explanatory value by illuminating how institutional
+    barriers (settlement laws) create artificial market segmentation and prevent natural
+    wage equilibration. It reveals an important mechanism linking policy constraints
+    to distributional outcomes rather than merely describing a surface phenomenon.
