S11: waveform view with draggable start/loop markers + zero-crossing snap

Browse Source 
Pure waveform_view module (frame<->pixel markers, zero-crossing snap); per-zone
loop/start overrides on PerformanceZone with self-versioning zone payload; core
start-point read offset; editor waveform surface with drag machine.
