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 clearly captures the concept of relative value changes
+    between gold, silver, and other commodities over time. It identifies specific
+    causal factors (mine abundance, different uses) without being circular, though
+    it could be slightly more precise about what constitutes "variation."
+- name: source_grounding
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity is directly grounded in Smith's extensive analysis in Book
+    I, Chapter 11, where he examines historical changes in gold-silver ratios and
+    their causes. The reference to American mines and different economic functions
+    of metals directly reflects Smith's detailed discussion.
+- name: domain_placement
+  value: 5.0
+  max_value: 5.0
+  rationale: The "Exchange" domain is perfectly appropriate since gold price variation
+    fundamentally concerns exchange ratios between different monetary metals and commodities.
+    This is a core exchange mechanism rather than production, distribution, or consumption.
+- name: vsm_relevance
+  value: 3.0
+  max_value: 5.0
+  rationale: This entity has moderate VSM relevance, primarily mapping to S4 (intelligence/environmental
+    adaptation) as it represents how economic systems detect and respond to changing
+    resource conditions. However, it's somewhat abstract and doesn't clearly embody
+    operational or regulatory functions.
+- name: explanatory_value
+  value: 4.0
+  max_value: 5.0
+  rationale: The entity provides good explanatory value by illuminating how relative
+    scarcity and functional demand create price mechanisms that affect monetary systems.
+    It reveals structural relationships between resource discovery, supply changes,
+    and value determination rather than merely naming a surface phenomenon.
