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.

Viability dashboard: 6/6 PASS
  redundancy_ratio   0.0061  (max 0.10)
  coverage_ratio     0.6190  (min 0.40)
  coherence_comps    0.0000  (max 3)
  consistency_cycles 0.0000  (max 0)
  granularity_entropy 2.6748 (min 1.0)
  per_entity_mean    3.9556  (min 3.5)

Dimension breakdown (mean across 985 entities):
  definition_precision  3.62
  source_grounding      4.36
  domain_placement      4.56
  vsm_relevance         3.31

+- name: definition_precision
+  value: 1.0
+  max_value: 5.0
+  rationale: There is no definition provided at all, making it impossible to assess

+    an empty placeholder.
+- name: source_grounding
+  value: 2.0
+  max_value: 5.0
+  rationale: While Smith does discuss agricultural improvements and technological
+    progress in "The Wealth of Nations," the specific framing of "technology adoption"
+    as a distinct analytical category may impose modern conceptual frameworks onto
+    18th-century economic thought. The absence of source chapter specification makes
+    verification impossible.
+- name: domain_placement
+  value: 3.0
+  max_value: 5.0
+  rationale: Agricultural technology would reasonably fall within economic analysis
+    of productivity and development, which aligns with Smith's concerns. However,
+    without domain specification or definitional content, proper categorization cannot
+    be confirmed.
+- name: vsm_relevance
+  value: 4.0
+  max_value: 5.0
+  rationale: Agricultural technology adoption could map well to S4 (intelligence/environmental
+    adaptation) as it represents how agricultural systems adapt to new knowledge and
+    environmental challenges. It might also relate to S1 (primary operations) in terms
+    of actual implementation of new techniques.
+- name: explanatory_value
+  value: 2.0
+  max_value: 5.0
+  rationale: While technological adoption is potentially an important mechanism for

+    underlying mechanisms or structural relations.
