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 is quite precise, clearly identifying specific types of
+    skilled workers (smiths, carpenters, etc.) and their function in serving agricultural
+    communities. It avoids circularity and captures a distinct economic phenomenon
+    of specialized service providers clustering around agricultural areas.
+- name: source_grounding
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity is well-grounded in Smith's actual text from Book III, Chapter

+    near agricultural areas to serve farmers' needs. The concept directly reflects
+    Smith's analysis of how market towns emerge from agricultural development.
+- name: domain_placement
+  value: 4.0
+  max_value: 5.0
+  rationale: The "Production" domain assignment is appropriate since these workers
+    are engaged in manufacturing and processing activities that transform raw materials
+    into finished goods. While they also involve exchange/trade elements, their primary
+    economic function is productive transformation.
+- name: vsm_relevance
+  value: 3.0
+  max_value: 5.0
+  rationale: This entity maps reasonably well to S1 (primary operations) as these
+    are the fundamental productive units that create value in the economy. However,
+    the entity also has coordination aspects (S2) as it describes how different specialists
+    coordinate to serve agricultural needs, making the VSM mapping somewhat ambiguous.
+- name: explanatory_value
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity provides excellent explanatory power by illuminating the

+    and the emergence of specialized manufacturing and service sectors.
