Add audiosync-wasm crate that compiles the FFT cross-correlation engine to WebAssembly for browser-based audio synchronization. Key changes: - Add feature flags to audiosync-core gating heavy deps (symphonia, reqwest, tokio, etc.) behind optional features - WASM build only includes core deps: rustfft, regex, serde, ndarray - Built WASM binary is ~330KB (optimized with wasm-opt) - Includes web demo page with drag-drop file import - Add useBackend.js abstraction layer for Tauri vs WASM runtime Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
