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: 2.0
+  max_value: 5.0
+  rationale: The definition is quite vague and umbrella-like, encompassing broad concepts
+    like "ways societies acquire knowledge" without clearly delineating what specifically
+    constitutes this learning process. It reads more like a general description of
+    social learning rather than a precise economic concept.
+- name: source_grounding
+  value: 2.0
+  max_value: 5.0
+  rationale: The entity claims to derive from "Book IV, Chapter 0" which doesn't exist
+    (Book IV doesn't have a Chapter 0), and the context provided is extremely thin,
+    suggesting Smith's "approach to explaining different systems implies" this concept
+    rather than explicitly discussing it. This appears to be an inference rather than
+    a clearly stated concept in the source.
+- name: domain_placement

+  max_value: 5.0
+  rationale: '"General Theory" is appropriate given the broad, abstract nature of

+    the vague nature of the concept itself.'
+- name: vsm_relevance
+  value: 4.0
+  max_value: 5.0
+  rationale: This entity maps well to S4 (intelligence/environmental adaptation) as
+    it describes how economic systems gather information and adapt based on learning
+    and experience. The learning process is fundamentally about intelligence gathering
+    and environmental scanning.
+- name: explanatory_value
+  value: 2.0
+  max_value: 5.0
+  rationale: The entity names a general phenomenon (learning about economics) but
+    doesn't illuminate any specific mechanism or provide insight into how economic
+    systems actually function or improve. It's too abstract to offer genuine explanatory
+    power about economic structures or processes.
