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: 4.0
+  max_value: 5.0
+  rationale: The definition clearly distinguishes nominal price from real price, specifying
+    it as monetary expression rather than labor-based measurement. It's precise and
+    non-circular, though could benefit from slightly more detail about what constitutes
+    "monetary terms."
+- name: source_grounding
+  value: 5.0
+  max_value: 5.0
+  rationale: This concept is directly grounded in Smith's Chapter 5 discussion of
+    real vs. nominal price, where he explicitly contrasts money prices with labor-based
+    value measures. The entity accurately reflects Smith's actual theoretical framework
+    without introducing foreign concepts.
+- name: domain_placement
+  value: 5.0
+  max_value: 5.0
+  rationale: '"Exchange" is the correct domain placement since nominal pricing is
+    fundamentally about how commodities are valued and traded in market transactions.
+    This concept sits at the heart of exchange mechanisms and price formation.'
+- name: vsm_relevance
+  value: 2.0
+  max_value: 5.0
+  rationale: This entity is largely VSM-neutral as it describes a measurement convention
+    rather than an operational or regulatory mechanism. While it might tangentially
+    relate to S1 operations where actual pricing occurs, it doesn't naturally map
+    to any specific VSM system function.
+- name: explanatory_value
+  value: 4.0
+  max_value: 5.0
+  rationale: The entity provides significant explanatory value by illuminating the
+    distinction between surface market phenomena (money prices) and underlying value
+    structures (labor content). This distinction is crucial for understanding Smith's
+    value theory and how markets function versus how they appear to participants.
