This change implements highly accurate virtual analog drum synthesis for TR-808 and TR-909 models based on deep DSP research. It replaces simplified models with precise oscillator configurations, frequency sweeps, and filtering. It also introduces a master bus processing chain with soft clipping and compression to achieve a cohesive 'analog' sound.

- Updated TR-808 and TR-909 Kick and Snare models with exact frequencies,
  envelopes, and techniques from the DSP research paper.
- Implemented the 808 Hi-Hat "Metallic Matrix" of 6 square oscillators
  and specific parallel bandpass filtering.
- Refactored DrumMachine to route all instruments through a master
  FX chain (Compressor -> WaveShaper -> Master Gain).
- Updated WaveShaper with the research-provided soft-clipping formula.
- Added micro-randomization (analog drift) to all drum models.
- Refactored routing to support dedicated open hi-hat output.
