feat: add react v19 to peer deps

[Yonom]

Thanks a lot for this package

I get the following warning from pnpm after upgrading to NextJS v15 (released today), which installs react 19 RC

React 19 is technically still in RC stage, but since a stable version of a major Metaframework is installing it, it's a sign that it's ready for production use and will now be used by many projects.

I think the ^19.0.0-rc bit may not be necessary. Is it?

[Yonom]

If you want to support NextJS 15 which currently installs the RC, then it is necessary

You can test: https://semver.npmjs.com/

That's interesting. I was testing using this tool which seemed to suggest that it was unnecessary. I guess it's safer to use the more conservative approach though

@bvaughn The other data point is radix-ui using the same, see:
https://github.com/radix-ui/primitives/blob/main/packages/react/dialog/package.json#L49

I am not sure about the way the package managers handle this, but generally 19.0.0 is considered higher than 19.0.0-rc.x, so if you specify "^19.0.0", you wouldn't want 19.0.0-rc (which was released before 19.0.0) to be accepted

Thanks for the PR~
