feat: Footswitch Modes — Stomp/Preset/Snapshot/Combo with scribble strips
Implements multi-mode footswitch system for the Helix Stadium-inspired pedal UI: - Footswitch mode context provider with 4 modes: stomp, preset, snapshot, combo - ModeSelector in status bar (collapsed cycling mode for mobile) - Stomp mode: footswitches toggle individual blocks on/off, scribble strips show block name + status - Preset mode: footswitches show Bank Up/Down + preset selection, scribble strips show preset name + number - Snapshot mode: footswitches recall 8 snapshots, scribble strips show snapshot name - Combo mode: first 4 stomp + bank nav + preset select + global bypass - ScribbleStrip LCD component with LED indicator and double-tap support - Double-tap gesture hook for secondary actions (tuner, snapshot save, etc.) - FootswitchBar container with 8 capacitive-touch footswitch buttons and LED rings - usePedalState hook (WebSocket + API polling, ported from frontend-react/App.jsx) - Dark pedal theme CSS (Helix-inspired) with responsive mobile layout - Full App.tsx rewrite with status bar, footswitch bar, tab bar, and all screens
