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

+  max_value: 5.0
+  rationale: The definition captures a coherent concept about long-term viability
+    of economic systems, but uses somewhat vague terms like "effectiveness" and "desired
+    outcomes" without specifying what these mean. The core idea of maintaining operations
+    without depleting foundational resources is reasonably precise.

+  max_value: 5.0
+  rationale: The entity acknowledges that sustainability is "not explicitly discussed
