fix(mq_editor): Catmull-Rom bezier fit, NaN guard, synth FFT toggle
- evalBezier: guard dt<=0 to avoid NaN on degenerate curves
- fitBezier: replace nearest-neighbor control points with Catmull-Rom
tangents (Hermite->Bezier), curve now passes through endpoints
- key 'a': toggle mini-spectrum between original and synth FFT
handoff(Claude): bezier fix + synth FFT comparison
