w1n5t0n 329b326ede feat(playground): per-engine param presets for additive + FM (meml-ax4) 
Additive engine: 5 presets across 3 tiers (Spectral Basics, Formant Play,
Harmonic Sculptor, Phase Explorer, Full Spectrum). FM engine: 5 presets
across 3 tiers (Simple FM, Bell Tones, Matrix Explorer, Feedback Machine,
Full Matrix).

Engine-aware preset system: applyPreset() dispatches to C15 groupOverrides
or new flat engineParamOverrides depending on active engine. Preset selector
dropdown rebuilds on engine switch. URL ?preset param searches all engines.

// FM synth presets for NISPS playground
// Each preset defines which params are active (ML-controlled) and which are
// muted at safe defaults. Param IDs match faustParamAddress() output from
// fm-matrix.json (e.g. 'operators_op_1_op1_ratio', 'matrix_m21').
//
// 3 tiers of progressive complexity across 5 presets.
