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

+  max_value: 5.0
+  rationale: The definition clearly distinguishes between two related but distinct
+    medieval practices - forestalling (buying before market) and engrossing (accumulating
+    stocks) - and explains their common purpose of market manipulation. The definition
+    is precise and non-circular, though it could benefit from slightly more specificity

+- name: source_grounding

+  rationale: This entity is well-grounded in Smith's actual text, particularly Book
+    IV where he extensively discusses these medieval commercial regulations as part

+- name: domain_placement

+    of how regulations can distort natural market processes.
+- name: vsm_relevance
+  value: 3.0
+  max_value: 5.0
+  rationale: This entity has moderate VSM relevance, primarily mapping to S2 (coordination)
+    as these regulations attempted to control market oscillations and price variations,
+    albeit counterproductively. It also touches on S3 (internal regulation) as a failed
+    regulatory mechanism, though the mapping is not as natural as more structural
+    economic concepts.
+- name: explanatory_value
+  value: 4.0
+  max_value: 5.0
+  rationale: This entity provides strong explanatory value by illustrating a specific
+    historical mechanism through which well-intentioned regulations can obstruct efficient
+    market development. It demonstrates Smith's broader argument about unintended
+    consequences of market intervention and helps explain the evolution from medieval
+    to modern commercial practices.
