Neoclassical deep pass + musical transitions round (merged)

neoclassical: felt piano (2/3+ lead+bass), strings swell pads (organ purged), contrary-motion counterpoint, pedal thunks, RUBATO as a real time dimension (beat-warp in buildEvents, all layers sample-locked, 0.15ms skew); margins vs ambient/newage +0 -> +6/+7

• transitions round (report lost to API error, edits verified in-tree + verify.sh green): sampler micro-lick transitions, 3-min evolution rule, soundfont liberalization, sweep demotion

Verified: verify.sh PASS 9.8s on merged tree
