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)

+- name: definition_precision
+  value: 4.0
+  max_value: 5.0
+  rationale: The definition is precise and clearly distinguishes excise duty drawback
+    from general drawbacks by specifying it applies to domestically produced goods
+    and excise duties specifically. It captures a distinct mechanism rather than a
+    vague concept, though it could be slightly more concise.
+- name: source_grounding
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity is well-grounded in Smith's actual discussion of drawbacks
+    in Book IV, Chapter 4, where he explicitly analyzes how drawbacks on excise duties
+    function and their role in maintaining natural economic balance. The concept directly
+    reflects Smith's own analysis rather than imposing external interpretations.
+- name: domain_placement
+  value: 5.0
+  max_value: 5.0
+  rationale: The "Regulation" domain assignment is entirely appropriate, as excise
+    duty drawbacks are a specific regulatory mechanism that government implements
+    to counteract the distortive effects of its own taxation policies. This fits perfectly
+    within Smith's broader discussion of commercial regulations.
+- name: vsm_relevance
+  value: 4.0
+  max_value: 5.0
+  rationale: This entity maps well to S2 (coordination/anti-oscillation) as it represents
+    a regulatory mechanism designed to prevent artificial distortions in capital allocation
+    and maintain economic balance. It also has some S3 (internal regulation) characteristics
+    as a corrective policy tool.
+- name: explanatory_value
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity provides excellent explanatory value by illuminating the
+    specific mechanism through which governments can neutralize the competitive disadvantages
+    their own taxation creates for domestic producers in export markets. It demonstrates
+    Smith's nuanced understanding of how regulatory interventions can sometimes preserve
+    rather than distort natural economic processes.
