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)

  granularity_entropy 2.6748 (min 1.0)
  per_entity_mean    3.9556  (min 3.5)

Dimension breakdown (mean across 985 entities):

+- name: definition_precision
+  value: 4.0
+  max_value: 5.0
+  rationale: The definition clearly distinguishes free ports as specific designated
+    locations with minimal customs duties, contrasting them with broader national
+    trade policies. It avoids circularity and captures a distinct institutional arrangement
+    rather than a vague concept.
+- name: source_grounding
+  value: 5.0
+  max_value: 5.0
+  rationale: The entity is directly grounded in Smith's discussion in Book IV, Chapter
+    3, where he explicitly examines free ports as examples of localized free trade
+    policies. The context accurately reflects Smith's observation about European towns
+    functioning as free ports while no entire countries adopt this approach.
+- name: domain_placement
+  value: 5.0
+  max_value: 5.0
+  rationale: The "Exchange" domain is perfectly appropriate since free ports are fundamentally
+    about facilitating trade and commercial exchange through reduced regulatory barriers.
+    This represents a core mechanism of market exchange rather than production, distribution,
+    or consumption.
+- name: vsm_relevance
+  value: 3.0
+  max_value: 5.0
+  rationale: Free ports have some VSM relevance as they represent a coordination mechanism
+    (S2) that manages trade flows and reduces friction between different regulatory
+    environments. However, they are primarily a policy tool rather than a core systemic
+    function, making the VSM mapping somewhat indirect.
+- name: explanatory_value
+  value: 4.0
+  max_value: 5.0
+  rationale: This entity illuminates an important structural mechanism showing how
+    localized free trade can coexist with broader protectionist policies, demonstrating
+    Smith's argument about the benefits of reduced trade barriers. It reveals the
+    institutional innovation of creating trade enclaves within otherwise restricted
+    economies.
