/**
 * Advanced barcode scanner with tap-to-focus, camera selection, and flash control.
 *
 * This class provides a complete barcode/QR code scanning solution with advanced
 * camera features including:
 * - Automatic camera selection (prioritizes back cameras with best focus capabilities)
 * - Tap-to-focus using contrast detection
 * - Manual focus distance control
 * - Flash/torch control
 * - Multiple camera switching
 * - iOS and Android support
 * - Multiple decoder backends (Native, ZBar)
 *
 * @example
 * ```typescript
 * import { WebBarcodeScanner, BarcodeDetectorType, BarcodeFormat } from '@your-package/barcode-scanner';
 *
 * const scanner = new WebBarcodeScanner({
 *   container: document.getElementById('scanner-container')!,
 *   debug: true,
 *   detectorType: BarcodeDetectorType.AUTO,
 *   formats: [BarcodeFormat.QR_CODE, BarcodeFormat.EAN_13],
 *   onCodeScanned: (code, format) => {
 *     console.log('Scanned:', code, 'Format:', format);
 *   },
 *   onError: (error) => {
 *     console.error('Error:', error.type, error.message);
 *   }
 * });
 *
 * await scanner.init();
 * ```
