Make zustand compatible with React 19

[dgtllion]

I see that zustand is supporting only <React18.
Is it possible to add React 19 in package.json? Or there are some work needed before that?

@dgtllion should work with React 19 without any issues but keep us in the loop if something went wrong

Thank you for your fast response.
I understand that it should work... What i mean when i try to add update React to 19 then i get incompatible warnings and one of them is zustand.

└─┬ zustand 5.0.1
  └── ✕ unmet peer @types/react@npm:types-react@19.0.0-rc.1: found 19.0.0-rc.1

Well if you for example want to use Zustand with NextJS 15, you get something like this.

It should work with 1.4.0.

Yes it seems to work but it's to remove the warning

It looks like you are using old version of zustand.

I got the same error (with the latest zustand version 5.0.2)
