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

+  rationale: The definition is precise and captures a distinct concept - metals as
+    exchange medium with specific properties (durability, divisibility, proportionality).

+- name: domain_placement

+- name: vsm_relevance
+  value: 3.0
+  max_value: 5.0
+  rationale: Metal currency maps most naturally to S1 (primary operations) as it's

+    by standardizing exchange processes. However, it's somewhat abstract as an exchange
+    medium rather than a clear systemic function.
+- name: explanatory_value

+  max_value: 5.0
+  rationale: This entity provides genuine explanatory power by illuminating the mechanism

+## definition_precision — 4.0 / 5.0

+The definition is precise and captures a distinct concept - metals as exchange medium with specific properties (durability, divisibility, proportionality). It avoids circularity and clearly distinguishes metal currency from other forms of exchange media.

+## source_grounding — 5.0 / 5.0
