Why do we need to support SubDoc?

• When opening a page, we only need to load the page data instead of the entire workspace data, which can improve performance.
• Support for permission control and sharing through fine-grained data control.

What work does this require us to do?

• First, upgrade the yrs version, the latest yrs version supports the sub-doc feature.
• Modify the yrs websocket communication protocol to support sub-doc message distribution.
• Modify existing server and client code to support the new data structure.
• Upgrade existing user data to the new data structure.

I prefer to track and move the issue in octobase.
