feat(playground/faust): full 48-param additive synth DSP (meml-pj4)
Replace placeholder stub with a complete additive synthesiser:
- 64 harmonics, 5 parameter groups (Spectral Shape, Temporal, Phase,
Modulation, Master), 48 NISPS-mapped params in exact spec order
- Spectral descriptors: per-harmonic amplitudes, tilt, inharmonicity,
odd/even balance, formant Gaussian shaping
- Temporal: dual ADSR (global + brightness), spectral flux LFO
- Phase: randomisation, walk, inter-partial beating, stereo spread,
noise floor with colour, sub-harmonic
- Modulation: vibrato (delayed onset), tremolo, harmonic drift,
formant resonance peaks
- Master: level, vel coupling, portamento, saturation waveshaper,
fine-tune cents
- additive-processor.js: AudioWorklet processor extending
FaustWorkletProcessor with dynamic zone-table construction at init,
_onNoteOn/Off, _renderBlock, _onSetParam
- additive.json: Faust descriptor with 48 params in spec-ordered groups
(numeric prefixes force alphabetical sort = spec order)
- additive.wasm: compiled with faust 2.83.1 -lang wasm -cn additive
