Changes

• ✨ Added initial React Native Web support by introducing a webpack.config.js in the example project.
• 🔧 Configured Babel and image loaders for web compatibility.
• 🛠️ Aliased react-native to react-native-web and set up module resolution for web-specific files.
• 🚀 Enabled development server with hot reloading for browser testing.
• 🌐 This is important to allow the SDK and example app to run and be tested directly in web browsers, expanding platform support.
