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 distinguishes between artificial and natural barriers
+    that prevent free flow of goods, with specific examples (political boundaries,
+    poor infrastructure, geographical barriers). It avoids circularity and captures
+    a distinct economic concept, though it could be slightly more precise about what

+- name: source_grounding
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity is directly grounded in Smith's text, specifically his discussion
+    of how nations controlling river territories can obstruct communication between
+    inland areas and the sea. The concept accurately reflects Smith's analysis of
+    how such obstructions limit commerce and market development.
+- name: domain_placement

+  max_value: 5.0
+  rationale: '"Regulation" is an appropriate domain since market obstructions often

+    barriers) are more structural. The placement captures the primary concern with
+    artificial barriers while acknowledging natural ones.'
+- 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 organizations must understand and adapt to market obstructions
+    in their environment. It could also relate to S2 (coordination) when obstructions
+    create coordination problems between system parts.
+- name: explanatory_value
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity provides excellent explanatory power by illuminating a key
+    mechanism that limits market extent and division of labor. It helps explain why
+    some regions remain economically underdeveloped and connects infrastructure, geography,
+    and policy to economic outcomes.
