/**
 * Guarded access to the OPTIONAL native modules used by the Apple Vision
 * backend: react-native-vision-camera + react-native-worklets-core.
 *
 * They are `peerDependenciesMeta.optional` — a host that only uses the
 * WebView runtime (the default, Expo Go compatible) does not install them.
 *
 * 1. Every `require` is wrapped in try/catch. Metro marks dependencies
 *    required inside a try block as *optional* when
 *    `transformer.allowOptionalDependencies` is enabled (the Expo default),
 *    so bundling never fails when a module is absent.
 * 2. The SDK must not depend on these packages' TypeScript types, so the
 *    interfaces below are minimal *structural* typings of the APIs we
 *    consume (react-native-vision-camera 4.x, worklets-core 1.x).
