Hi, This PR introduces changes to modernize the React Native architecture, yi…elding significant improvements in native performance and enabling bridgeless mode compatibility (see [https://reactnative.dev/architecture/landing-page#fast-javascriptnative-interfacing](https://reactnative.dev/architecture/landing-page#fast-javascriptnative-interfacing) for more information). Migrating to these updated packages ensures long-term support, alignment with modern React Native standards, and enhanced performance for future project development. **Package Updates:** * **`react-native-fs` -> `@dr.pogodin/react-native-fs`:** This migration replaces the original package with a version that supports the new React Native architecture and is actively maintained. Refer to the project history and roadmap here: [https://github.com/birdofpreyru/react-native-fs?tab=readme-ov-file#project-history--roadmap](https://github.com/birdofpreyru/react-native-fs?tab=readme-ov-file#project-history--roadmap). An additional benefit is improved tree shaking capabilities. * **`@react-native-async-storage/async-storage` -> `react-native-mmkv`:** This change leverages the new React Native architecture through Turbo Modules, resulting in substantial performance gains. `react-native-mmkv` is approximately 25x faster than `@react-native-async-storage/async-storage`. Benchmark details can be found here: [https://github.com/mrousavy/react-native-mmkv?tab=readme-ov-file#benchmark](https://github.com/mrousavy/react-native-mmkv?tab=readme-ov-file#benchmark). * **Expo Packages:** All Expo-related packages have been updated to their latest versions. Importantly, `expo-camera` has been migrated from the legacy (deprecated) version to the new version (`expo-camera-next`). This new version uses an improved camera API under the hood. See more details here: [https://expo.dev/blog/expo-camera-next#our-goals-for-expo-cameranext](https://expo.dev/blog/expo-camera-next#our-goals-for-expo-cameranext). Release Strategy Suggestion: As for the release, I suggest we can either release this update with a `@beta` tag to allow users to test the changes before the final release or we can update all relevant documentation and introduce this as a *breaking change* for the next major version. This will give us the flexibility to properly communicate the changes and ensure a smooth upgrade path for the users. Please review these changes and let me know if you identify any issues or potential areas for improvement. Your feedback is greatly appreciated.
