Procedural Drum Synthesis and Patterns Implementation

[Pitrat-wav]

This PR implements a high-fidelity procedural drum synthesis engine and pattern generator based on the provided deep DSP research. Key highlights:

1. Authentic DSP Synthesis: Replaced sample-based components with procedural models for TR-808 and TR-909. This includes:
   • TR-909 Snare: Authentic 15-bit LFSR noise implementation and dual triangle oscillator body with precise pitch sweeps.
   • TR-808/909 Kicks: Refined pitch envelopes and saturation curves (WaveShaper) for maximum punch.
   • TR-808 Hi-Hats: 6-oscillator square wave matrix with parallel bandpass filtering.
2. Drum Patterns & Randomization:
   • Set up "techno foundation" default Euclidean patterns.
   • Implemented a "Randomize" (Dice) feature that generates musical patterns and immediately syncs them with the audio engine.
3. Telegram Mini App Optimization:
   • Added haptic feedback (impactOccurred) on the downbeat (step 0) and when using the randomization feature.
   • Minimized memory footprint by reusing noise buffers and ensuring explicit node disposal.
4. Stability & UX:
   • Fixed TypeScript mapping issues in the DrumMachine.
   • Synced initial instrument parameters from the store on launch.
   • Improved visibility of UI controls.
