AI-Generated Summary: This pull request provides preliminary support for rendering custom cursors within the yjs package. This update doesn't have any default rendering included yet, neither does it update active users. This patch specifically adds a new file, RemoteCursorOverlay.tsx, in the yjs package which contains logic for rendering the cursor overlay. Changes have also been made to package.json in yjs, providing an additional dependency for @slate-yjs/react. Lastly, the RemoteCursorOverlay was exported in the index file of the yjs package.
