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):

  domain_placement      4.56
  vsm_relevance         3.31

+- name: definition_precision
+  value: 2.0
+  max_value: 5.0
+  rationale: The definition is overly broad and umbrella-like, encompassing "individuals,
+    organizations, and entities" without clear boundaries or distinguishing characteristics.
+    It reads more like a general category than a precise concept that captures a distinct
+    analytical unit.
+- name: source_grounding
+  value: 2.0
+  max_value: 5.0
+  rationale: While Smith certainly discusses various economic actors throughout The
+    Wealth of Nations, this entity appears to be a modern analytical construct rather
+    than a concept Smith explicitly develops. The attribution to "Book IV, Chapter
+    0" is problematic since Book IV doesn't have a Chapter 0, and the definition seems
+    to impose contemporary frameworks on Smith's text.
+- name: domain_placement
+  value: 3.0
+  max_value: 5.0
+  rationale: '"General Theory" is appropriate given the broad nature of this entity,

+    The entity is too abstract to clearly belong to a more specific economic domain.'
+- name: vsm_relevance
+  value: 1.0
+  max_value: 5.0
+  rationale: This entity is far too abstract and general to map meaningfully to any
+    specific VSM system - it could theoretically encompass actors across all systems
+    S1-S5. The concept lacks the structural specificity needed for useful VSM mapping.
+- name: explanatory_value
+  value: 2.0
+  max_value: 5.0
+  rationale: The entity provides minimal explanatory power beyond simply naming the
+    obvious fact that economic systems have participants. It doesn't illuminate specific
+    mechanisms, relationships, or structural dynamics that would advance understanding
+    of Smith's political economy.
