/**
 * Native camera view for real-time face detection and matching.
 *
 * This component renders a camera preview with face detection overlay.
 * Frames are processed natively without crossing the JS bridge.
 *
 * @example
 * ```tsx
 * // Matching mode
 * <FaceDetectionCameraView
 *   mode="matching"
 *   enableMatching={true}
 *   targetEmbedding={userEmbedding}
 *   matchThreshold={1.1}
 *   onMatchResult={({ nativeEvent }) => {
 *     if (nativeEvent.isMatch) {
 *       console.log('Face matched!');
 *     }
 *   }}
 *   style={{ flex: 1 }}
 * />
 *
 * // Enrollment mode
 * <FaceDetectionCameraView
 *   mode="enrollment"
 *   capturePhoto={shouldCapture}
 *   onEnrollmentStatus={({ nativeEvent }) => {
 *     console.log(nativeEvent.instruction);
 *   }}
 *   onEnrollmentCapture={({ nativeEvent }) => {
 *     console.log(`Photo ${nativeEvent.photoIndex + 1} captured`);
 *   }}
 *   onEnrollmentComplete={({ nativeEvent }) => {
 *     if (nativeEvent.success) {
 *       saveEmbedding(nativeEvent.embedding);
 *     }
 *   }}
 *   style={{ flex: 1 }}
 * />
 * ```
