This commit replaces sample-based logic with authentic virtual analog synthesis for TR-808 and TR-909 kits. - Added 15-bit LFSR and white noise generation utilities. - Implemented multi-stage frequency and amplitude envelopes for Kicks. - Optimized Snare and Clap models with random start offsets to eliminate repetition artifacts. - Improved memory management with robust node disposal across all drum modules. - Set techno-focused default Euclidean patterns.

Changing the store default to kit: '909' makes the UI and persisted drum state start on 909, but DrumMachine.currentKit still initializes to '808' and initialize() only constructs new DrumMachine(); the only code path that calls drumMachine.setKit(...) is the DrumsView click handler. In a fresh session before the user toggles kits, triggerDrum therefore routes to the 808 instruments while the UI shows 909, so the new default kit setting is not actually applied to playback.
