730d045c71 Restore lint corrections from #7989 (#7997) 
* Ignore braces when building Sandpack file map

Previously, `createFileMap` split the MDX meta string on spaces and assumed the first token was the filename. Once we prefixed code fences with `{expectedErrors: ...}`, it would incorrectly parse the meta and crash.

This PR updates createFileMap to skip tokens in the meta containing a start and end brace pair (using a stack to ensure we close on the correct brace) while tokenizing the meta string as expected.

Test plan: pages reported in #7994 no longer crash on the next PR

Closes #7994

* Restore lint corrections from #7989

Reverts the revert now that we've fixed the bug. These pages should no longer crash:

5cc9b7ba31 fix compiler errors (#7989) 
* Add local eslint rule to validate markdown codeblocks with React Compiler

In https://github.com/facebook/react/pull/34462 for example, we found an issue where the compiler was incorrectly validating an example straight from the docs.

In order to find more issues like this + also provide more feedback to doc authors on valid/invalid patterns, this PR adds a new local eslint rule which validates all markdown codeblocks containing components/hooks with React Compiler. An autofixer is also provided.

To express that a codeblock has an expected error, we can use the following metadata:

```ts
// pseudo type def
type MarkdownCodeBlockMetadata = {
    expectedErrors?: {
      'react-compiler'?: number[];
    };
  };
```

and can be used like so:

````
```js {expectedErrors: {'react-compiler': [4]}}
// ❌ setState directly in render
function Component({value}) {
  const [count, setCount] = useState(0);
  setCount(value); // error on L4
  return <div>{count}</div>;
}
```
````

Because this is defined as a local rule, we don't have the same granular reporting that `eslint-plugin-react-hooks` yet. I can look into that later but for now this first PR just sets us up with something basic.

* fix compiler errors

I went through the list of existing errors and tried to separate the expected errors from those that seem to be flagging unexpected issues.  In particular, our effects validations are flagging patterns that our own docs examples use. I added todos for these and will follow up later.

d52b3ec734 Fix deadlinks (#7880) 
* [be] Add deadlinks script

While rewriting the compiler docs I happened to notice some deadlinks. This PR adds a new `yarn deadlinks` script to identify all deadlinks.

I decided to make this a script for now for simplicity but in the future could be ported to an ESlint rule.

The script handles:

- [x] checks images correctly (images are stored in /public but links can omit the /public)
- [x] looks up React error codes for dynamic error pages
- [x] lints links to contributors and uses URL from acknowledgements page if the member is no longer active on the core team
- [x] special injected anchor tags like #recap and #challenges

Example:

```
yarn run v1.22.22
$ node scripts/deadLinkChecker.js
