Provide DevTools through Chrome extension

[chacha912]

Description:

In the examples in the public folder, there are monitoring tools for text data type and document.root.

index.html (codemirror)	whiteboard.html

To enhance development convenience, create a Chrome extension that incorporates these tools.
This extension will provide an interface for monitoring and debugging.(Refer to: https://liveblocks.io/devtools)

• Considerations: The opsForTest, which monitors the entire operation, is currently designed to operate only in the development environment.

Why:

• Improved accessibility and usability of monitoring tools.
• Enhanced development experience for handling root and text data types.
