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: 3.0
+  max_value: 5.0
+  rationale: The definition identifies a distinct concept as one of two systems of
+    political economy focused on agricultural development, but it lacks specificity
+    about what constitutes this system's mechanisms or principles. The contrast with
+    the commercial system provides some clarity, but the definition remains somewhat
+    general.
+- name: source_grounding
+  value: 4.0
+  max_value: 5.0
+  rationale: The entity is well-grounded in Smith's actual text from Book IV, Chapter
+    0, where he explicitly discusses two distinct systems of political economy and
+    mentions the agricultural system as an alternative to commerce. The context accurately
+    reflects Smith's stated intention to explain both systems.
+- name: domain_placement
+  value: 5.0
+  max_value: 5.0
+  rationale: The "Production" domain assignment is highly appropriate since the agricultural
+    system fundamentally concerns land cultivation and agricultural development as
+    the primary means of wealth creation. This clearly falls within production-focused
+    economic activity.
+- name: vsm_relevance
+  value: 2.0
+  max_value: 5.0
+  rationale: This entity represents a high-level economic philosophy or approach rather
+    than a specific operational or regulatory mechanism, making it difficult to map
+    to any particular VSM system. It's too abstract and strategic to fit naturally
+    into the VSM framework's operational categories.
+- name: explanatory_value
+  value: 3.0
+  max_value: 5.0
+  rationale: The entity provides moderate explanatory value by establishing one of
+    two fundamental approaches to political economy that Smith analyzes, helping to
+    structure understanding of different wealth-creation philosophies. However, without
+    more detail about the system's specific mechanisms, its explanatory power remains
+    limited to broad categorization.
