Mike Vitousek e78c9362c0 [compiler] Allow all hooks to take callbacks which access refs, but ban hooks from taking direct ref value arguments
Summary:
This brings the behavior of ref mutation within hook callbacks into alignment with the behavior of global mutations--that is, we allow all hooks to take callbacks that may mutate a ref. This is potentially unsafe if the hook eagerly calls its callback, but the alternative is excessively limiting (and inconsistent with other enforcement).

This also bans *directly* passing a ref.current value to a hook, which was previously allowed.

babel-plugin-react-compiler

React Compiler is a compiler that optimizes React applications, ensuring that only the minimal parts of components and hooks will re-render when state changes. The compiler also validates that components and hooks follow the Rules of React.

This package contains the React Compiler Babel plugin use in projects that make use of Babel. You can find instructions for using this plugin here: https://react.dev/learn/react-compiler
