This PR implements a full overhaul of the drum synthesis engine to align with the provided DSP research on TR-808 and TR-909 emulation. Key changes include the introduction of 15-bit LFSR noise for 909 instruments, a two-stage amplitude envelope for the 808 Kick to simulate diode damping, and improved engine synchronization. Additionally, it enhances the Telegram Mini App experience with optimized default techno patterns and haptic feedback on pattern randomization and downbeats.


PR created automatically by Jules for task 17741414162315305432 started by @Pitrat-wav

- Added `generateLFSRNoise` to `DrumUtils.ts` for authentic 909 digital noise.
- Refined `TR808Kick.ts` with a two-stage amplitude envelope emulating diode damping.
- Updated `TR909Snare.ts` to use LFSR noise and proper filtering.
- Implemented `syncInternalParams` in `DrumMachine.ts` for robust engine-UI synchronization.
- Optimized default Euclidean patterns for a techno rhythm in `instrumentStore.ts`.
- Added 'Randomize Techno' feature with Dice icon and Telegram Haptic Feedback in `DrumsView.tsx`.
- Integrated light haptic feedback on the downbeat in `SequencerLoop.tsx`.
