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 between building rent and ground
+    rent components, and precisely explains how the tax burden is distributed between
+    inhabitants and ground owners. It avoids circularity and captures a specific tax
+    mechanism rather than a vague concept.
+- name: source_grounding
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity is directly grounded in Smith's detailed analysis in Book
+    V, Chapter 2, where he explicitly discusses house rent taxes and their differential
+    effects on building versus ground rent. The distinction between these rent components
+    and their tax incidence is a core part of Smith's taxation theory.
+- name: domain_placement
+  value: 5.0
+  max_value: 5.0

+    It fits naturally within his broader analytical approach to taxation principles.'
+- name: vsm_relevance
+  value: 3.0
+  max_value: 5.0
+  rationale: This entity has moderate VSM relevance, potentially mapping to S3 (internal

+    tax instrument rather than a fundamental system component.
+- name: explanatory_value
+  value: 4.0
+  max_value: 5.0
+  rationale: The entity provides strong explanatory value by illuminating the mechanism
+    of tax incidence distribution and how different types of rent respond differently
+    to taxation. It reveals structural relationships between property ownership, rental
+    markets, and tax burden rather than merely naming a surface phenomenon.
