* Update conferences.md for CityJS Athens and London Events Dear people, I would really appreciate if you include our community events on your website. It might not be titled as React conferences but it does have a lot of React on it! Thank you it is very much appreciated. * Update conferences.md Removed spaces as requested.
Reuses the main repo's workflow to label if a PR is opened by a core team member.

The previous examples used a service called loremflickr.com to link to placeholder images. Since that service is now down, I updated them to reference placecats.com instead, which we already use in other examples as well. placecats doesn't have the same random cat feature so I roughly approximated it in the example code. Closes #7966
* Fix handleClick compiler intro example * Use a note instead * Update src/content/learn/react-compiler/introduction.md
* fix: changed source file names in docs from App.js, index.js and styles.css to src/ dir * fix: updated wrong image with the correct one with current sandbox file structure * refactor: reverted all formatting and just just mention src folder in introductory section * Reverted changes tutorial-tic-tac-toe.md * added enhanced image of sandbox
* docs: add flushSync Troubleshooting section * Update src/content/reference/react-dom/flushSync.md * oops * Apply suggestions from code review * formatting and pitfall --------- Co-authored-by: Ricky <rickhanlonii@gmail.com> Co-authored-by: Rick Hanlon <rickhanlonii@meta.com>

Happened to notice we were still on an old version of the compiler. This PR upgrades us to use the latest RC.
Copied over our copyright script from the react repo. I made a small fix to handle shebangs.

…iler (#7988) In facebook/react#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.

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.
This reverts commit 5cc9b7b.
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
* Ignore braces when building Sandpack file map

For local dev and CI we want to have the eslint-local-rules running, so let's make sure both have their dependencies installed. We don't use a monorepo setup here, which is why they're currently setup as a two completely independent yarn workspaces.
Adds new docs for our new eslint rules.
