Mellotron sampler-mode + hammond joins the verifier's acoustic list

PART A — Mellotron tape mode on the native sampler, both engines: wow (~0.7Hz) + flutter (~7Hz) semitone undulation on playbackRate, 8s tape-strip cap with tape-runs-out pitch sag, gentle head-EQ.

• PART B — measured both ways, then decided: hammond (a tonewheel organ, genuinely electro-mechanical) joins genre-verifier's acoustic model-list at organ-grade .6

Verified: verify.sh PASS both parts: matrix 63/63, validate, engine smoke.
