Bug: Support Zod v4 in eslint-plugin-react-hooks

[RampantDespair]

React version:
N/A (ESLint issue)

Steps To Reproduce

1. Install eslint@9.36.0 with eslint-plugin-react-hooks@6.1.0 in a project that also uses zod@4.x.
2. Run ESLint on any file.
3. Observe the crash.

Link to code example:

Minimal reproduction:

npm init -y
npm i -D eslint@9.36.0 eslint-plugin-react-hooks@6.1.0 zod@4
npx eslint --init
npx eslint index.js

The current behavior

ESLint crashes with:

TypeError: zod.z.function(...).args is not a function
    at eslint-plugin-react-hooks.development.js:32075:57

This happens because eslint-plugin-react-hooks is written against Zod v3, where z.function(...).args(...) exists. In Zod v4, that API changed, so the plugin immediately fails when loaded.

The expected behavior

eslint-plugin-react-hooks should work with Zod v4, or at least specify a peer dependency constraint to prevent incompatible installs. Ideally the schema validation should be updated to use Zod v4’s function API.
