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.

+- name: definition_precision
+  value: 5.0
+  max_value: 5.0
+  rationale: The definition is highly precise and non-circular, clearly specifying
+    bills of exchange as written orders directing future payment between merchants.
+    It captures a distinct financial instrument with specific characteristics rather
+    than a vague concept.
+- name: source_grounding
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity is directly grounded in Smith's text, as he explicitly discusses
+    bills of exchange in Book II, Chapter 2 as instruments of commercial credit that
+    banks discount. The definition accurately reflects Smith's analysis of their role
+    in facilitating trade without immediate cash payment.
+- name: domain_placement
+  value: 5.0
+  max_value: 5.0
+  rationale: The "Exchange" domain assignment is perfectly appropriate, as bills of
+    exchange are fundamentally instruments that facilitate the exchange of value across
+    time and space. This placement correctly categorizes the entity within commercial
+    and financial exchange mechanisms.
+- name: vsm_relevance
+  value: 4.0
+  max_value: 5.0
+  rationale: Bills of exchange map well to S1 (primary operations) as they are operational
+    tools that enable basic commercial transactions, and to S2 (coordination) as they
+    coordinate payment flows between different merchants and locations. They serve
+    as concrete mechanisms within the viable system of commerce.
+- name: explanatory_value
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity provides excellent explanatory value by illuminating the
+    specific mechanism through which merchants could conduct trade without immediate
+    cash, showing how credit instruments enable capital circulation. It reveals a
+    structural relation between banking, credit, and commercial operations that is
+    central to Smith's analysis.
