This PR implements a full drum party synthesis and sequencing logic based on the 'Deep DSP Analysis of Analog Drum Synthesis' research. It replaces sample-based placeholders with high-fidelity procedural models for TR-808 and TR-909 instruments, ensures sample-accurate state synchronization, and adds a techno-optimized randomization feature for immediate groove generation.

… DSP research.

- Added 15-bit LFSR noise generator for authentic 909 digital textures.
- Refined 808 Kick with two-stage pitch/amp envelopes (diode damping).
- Increased 909 Kick saturation for improved harmonic density.
- Implemented bulk parameter synchronization between UI and audio engine.
- Added 'Randomize Techno' feature with haptic feedback and optimized patterns.
- Integrated downbeat haptic triggers in the sequencer loop.

P2 Badge Include clap in the techno randomizer

This partial Zustand update resets every drum lane except clap, and handleRandomize then syncs the engine with the unchanged s.clap. If a user previously changed the clap pulses/probability, especially to 0, pressing the dice leaves the clap stale or silent while the rest of the techno kit is reset, so add a clap entry to the randomized state.
