Adds `target: 'donotuse_meta_internal'`, which inserts useMemoCache imports directly from `react`. Note that this is only valid for Meta bundles, as others do not [re-export the `c` function](https://github.com/facebook/react/blob/5b0ef217ef32333a8e56f39be04327c89efa346f/packages/react/index.fb.js#L68-L70). ```js // target=donotuse_meta_internal import {c as _c} from 'react'; // target=19 import {c as _c} from 'react/compiler-runtime'; // target=17,18 import {c as _c} from 'react-compiler-runtime'; ``` Meta is a bit special in that react runtime and compiler are guaranteed to be up-to-date and compatible. It also has its own bundling and module resolution logic, which makes importing from `react/compiler-runtime` tricky. I'm also fine with implementing the alternative which adds an internal stub for `react-compiler-runtime` and [bundles](https://github.com/facebook/react/blob/5b0ef217ef32333a8e56f39be04327c89efa346f/scripts/rollup/bundles.js#L120) the runtime for internal builds.

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
