Subject: [PATCH] add react-native export condition resolving to browser build

Metro (React Native's bundler) resolves package exports with the
conditions `import`/`require` and `react-native`, never `browser`
or `node`, so it falls through to the `default` entry. That build
does `import('node:diagnostics_channel')`, which cannot be provided
in a React Native runtime. Current Metro treats the `.catch()`-
guarded import as optional at build time, but on native the runtime
`require` of an unresolved optional module reports a fatal error via
`ErrorUtils` instead of throwing, so the `.catch()` never runs and
the app crashes on startup.

Expose the existing browser build under the `react-native` condition
as well. This is the conventional way for packages to provide a
Metro-specific entry, is ignored by every other resolver, and adds
no new build output.
