Remove react-native related dependencies

# Feature Request

The react-native dependencies adds 200MB to npm installs (react-native-webview, react-native, @react-native-async-storage/async-storage). It's more than 10x bigger than any other dependency. This makes anything that uses this package to need 500mb+ in wasted storage. Can you please find a way to include this type of dependency without pulling in react-native packages?

## Why it is needed

Reduce slow npm install times and hugely wasted disk space since most projects won't be using react-native.

No files, tests, or entry points are named. Start by tracing where the package declares react-native, react-native-webview, and @react-native-async-storage/async-storage, then determine how React Native support can remain available without installing them for other consumers. Done means npm installs no longer pull in those dependencies while the React Native integration still works.
