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)

  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 articulates a distinct principle about economic
+    freedom leading to efficient resource allocation. While it could be more precise
+    about what constitutes "artificial restrictions," it avoids circularity and captures
+    a coherent concept.
+- name: source_grounding
+  value: 3.0
+  max_value: 5.0
+  rationale: The entity acknowledges that the concept is "not fully developed in this
+    chapter" and relies on implications rather than explicit statements from Smith.
+    While the principle of natural liberty is central to Smith's work, this specific
+    formulation may extrapolate beyond what Book IV, Chapter 1 directly states.
+- name: domain_placement
+  value: 5.0
+  max_value: 5.0

+    economic exchanges. This is precisely what the Exchange domain should encompass.'
+- name: vsm_relevance
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity maps excellently to S5 (identity/policy) as it represents
+    a fundamental organizing principle that guides how an economic system should operate.
+    It also has clear connections to S4 (intelligence/adaptation) as it describes
+    how market forces process information to allocate resources.
+- name: explanatory_value
+  value: 4.0
+  max_value: 5.0
+  rationale: The entity provides genuine explanatory power by identifying the mechanism
+    through which individual freedom leads to collective prosperity via market forces.
+    It illuminates a key structural principle rather than merely naming a surface
+    phenomenon, though the mechanism could be elaborated further.
