Add Oscillator::setParams() which updates detune, pan, and gain for already-initialised sub-voices without resetting their phases. This preserves phase continuity when unison or spread is LFO-modulated at control rate. noteOn() now just seeds phases and delegates to setParams(). Precompute panL/panR in SubVoice instead of calling cos/sin per sample. Add paramsValid and cachedParams to skip redundant work. Replace SynthVoice's lastUnisonA/B tracking with a single oscillatorsNeedNoteOn flag: noteOn sets it, render clears it after the first block. Add SubLevel and NoiseLevel to the per-voice modulation targets so they can be modulated like other parameters.
