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):

+- name: definition_precision
+  value: 4.0
+  max_value: 5.0
+  rationale: The definition clearly distinguishes between the narrow, protectionist
+    mindset of small-scale merchants versus the efficiency-seeking approach of larger
+    traders. It precisely captures the concept of prioritizing exclusive relationships
+    over market efficiency, though it could be slightly more concise.
+- name: source_grounding
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity is directly grounded in Smith's explicit contrast between
+    "great traders" and "underling tradesmen" in Book IV, Chapter 3, where he criticizes
+    applying small merchant principles to national policy. The terminology and conceptual
+    distinction come straight from the source text.
+- name: domain_placement
+  value: 5.0
+  max_value: 5.0
+  rationale: The "Exchange" domain is perfectly appropriate since this concept deals
+    fundamentally with trading relationships, market access, and commercial principles.
+    The entity concerns how different types of merchants approach exchange relationships
+    and market participation.
+- name: vsm_relevance
+  value: 3.0
+  max_value: 5.0
+  rationale: This entity has moderate VSM relevance, primarily relating to S4 (intelligence/environmental
+    adaptation) as it concerns how economic actors gather market intelligence and
+    adapt to competitive environments. However, it's more of a behavioral pattern
+    than a clear systemic function.
+- name: explanatory_value
+  value: 4.0
+  max_value: 5.0
+  rationale: The entity provides strong explanatory value by illuminating a key mechanism
+    in Smith's critique of mercantilism - how small-scale merchant thinking inappropriately
+    scales up to national policy. It helps explain why certain protectionist policies
+    emerge and why Smith considers them misguided.
