Add docs for react-devtools-cdt-mcp

[hoxyq]

Adds a minimal docs for react-devtools-cdt-mcp, the experimental library that exposes React DevTools data to agents through Chrome DevTools MCP.

Aa new experimental reference page, React DevTools for agents (/reference/dev-tools/react-devtools-cdt-mcp), is listed under React DevTools in the reference sidebar. It covers:

• an overview of how the package works with Chrome DevTools MCP
• setup, including importing the package before React and a link to the Chrome DevTools MCP docs for configuration
• a live Try it sandbox that runs fully in the browser
• a summary list of the 12 tools, plus register()
• troubleshooting

How: the sandbox imports react-devtools-cdt-mcp/register like a real app would. A small hidden tool console then discovers the tools the same way Chrome DevTools MCP does, by dispatching the devtoolstooldiscovery event, so readers can call every tool without an extension or an MCP server.

Known issue: Sandpack's package CDN doesn't know about react-devtools-cdt-mcp@0.1.0 yet. It returns "Package version not found", so the sandbox pins 0.0.1, which has the same 12 tools. Bump the pin once the CDN picks up the new version.

One Page Changed Size

The following page changed size from the code in this PR compared to its base branch:

Page	Size (compressed)	First Load

Details

Only the gzipped size is provided here based on an expert tip.

First Load is the size of the global bundle plus the bundle for the individual page. If a user were to show up to your website and land on a given page, the first load size represents the amount of javascript that user would need to download. If next/link is used, subsequent page loads would only need to download that page's bundle (the number in the "Size" column), since the global bundle has already been downloaded.

Any third party scripts you have added directly to your app using the <script> tag are not accounted for in this analysis

Next to the size is how much the size has increased or decreased compared with the base branch of this PR. If this percentage has increased by 10% or more, there will be a red status indicator applied, indicating that special attention should be given to this.
