Thanks @rveciana for the contribution!

I see you have updated the devDependencies of the monorepo, but the @react-rxjs/core pacakge is left untouched, aside from linting/prettier changes.

I think we have to update the peerDependency of @react-rxjs/core to declare it's compatible with react@19

Thanks again @rveciana!

It looks good to me, but you have removed some generics on the test files that gives me TS errors on my IDE - I tried adding a commit fixing those to this PR but I couldn't, you can cherry-pick it if you want: 6923301

The CI is failing for an unrelated issue with some code coverage tool we have, I'll take a look as a separate issue.

Thanks for finding this. A wrong vscode configuration did it.
