feat(tradein): same-building anchor estimator (#651/#652 v2) behind flag
Replaces radius-median ppm2 with a same-building anchor (Tier A: normalized
street+house comps; Tier C: <=500m segment-matched; Tier D: existing radius
fallback). Similarity-weighted mean + guarded premium uplift + ppm2-banded
asking->sold haircut + hard guardrail + tightened FSD range. Fixes ~2.5x
premium underestimate / 15-25% comfort dilution. Address normalizer handles
e->e, Tkacheva->Tkachey alias, base-house-number across corpus letters.
Behind estimate_same_building_anchor_enabled (default on); OFF = prior behavior.
Validated offline (55 golden: coverage 53->95%, premium medAPE 53->18%) + 4 live cases.
19 new tests; full suite 1106 passed; ruff clean.
