This PR implements advanced procedural drum synthesis for the TR-808 and TR-909 kits, following the provided DSP research.

Key improvements include:

  • TR-808 Kick: Implemented a non-linear two-stage frequency sweep and a two-stage amplitude envelope to emulate the physical behavior of the Bridged-T network and diode damping.
  • TR-909 Snare: Added an authentic 15-bit LFSR (Linear Feedback Shift Register) noise generator for the 'snappy' component, matching the original hardware's digital noise characteristic.
  • Engine-UI Synchronization: Introduced syncInternalParams to ensure the audio engine correctly reflects the initial React state upon launch.
  • Telegram Integration: Created a robust WebApp wrapper in src/telegram.ts with full mocks, improving stability in non-Telegram environments and simplifying haptic/UI interactions.
  • UX: Added a 'Randomize Techno' button with haptic feedback and optimized default patterns for an immediate techno groove.
  • Code Health: Standardized naming conventions (e.g., cowbell volume key) and improved node disposal patterns to prevent memory leaks.

- Enhanced TR-808 Kick with two-stage pitch sweep and amplitude envelope for diode damping emulation.
- Integrated 15-bit LFSR pseudo-random noise in TR-909 Snare for authentic digital snappy texture.
- Increased TR-909 Kick saturation for improved punch.
- Centralized Telegram WebApp API with mocks in `src/telegram.ts` to ensure build stability and browser compatibility.
- Synchronized audio engine state with UI on initialization.
- Added 'Randomize Techno' feature and haptic feedback to the drum machine.
- Optimized default Euclidean patterns for techno rhythms.
- Standardized volume key names across the store and UI components.

P2 Badge Guard optional Telegram WebApp methods before calling

On Telegram clients that expose window.Telegram.WebApp but do not include newer helpers such as disableVerticalSwipes (the previous code treated these methods as optional), this mount effect throws a TypeError before the app can initialize. The mock only applies outside Telegram, so real clients with a partial WebApp API still need optional guards or no-op fallbacks in the wrapper.
