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: 3.0
+  max_value: 5.0
+  rationale: The definition captures a recognizable concept about social acceptance
+    of economic systems, but it's somewhat broad and could apply to many institutional
+    arrangements. While not circular, it lacks the precision to clearly distinguish
+    this from related concepts like political authority or social contract.
+- name: source_grounding
+  value: 2.0
+  max_value: 5.0
+  rationale: The entity extrapolates significantly from Smith's brief mention of political
+    economy being a science for statesmen and legislators. Smith doesn't explicitly
+    discuss "legitimacy" as a distinct concept, and this appears to impose modern
+    political science terminology onto his work.
+- name: domain_placement

+  max_value: 5.0
+  rationale: '"General Theory" is appropriate since legitimacy would be a foundational

+    economic systems generally.'
+- name: vsm_relevance
+  value: 4.0
+  max_value: 5.0
+  rationale: This entity maps well to S5 (identity/policy) as legitimacy is fundamentally

+    stakeholders. It could also relate to S4 in terms of environmental adaptation
+    to social expectations.
+- name: explanatory_value
+  value: 2.0
+  max_value: 5.0
+  rationale: While legitimacy is important for understanding economic systems, this
+    entity doesn't illuminate specific mechanisms or structural relations that Smith
+    analyzes. It names a general condition rather than explaining how economic processes
+    actually work or interact.
