Pull request overview

This PR implements a collaboration toggle feature that disables collaboration by default until explicitly enabled by the user. The implementation includes significant dependency upgrades (Turbo v1 to v2), refactoring of identity management from Context API to Jotai atoms, and a new UI for managing sharing settings.

• Upgrades Turbo from v1.10.x to v2.7.2 with corresponding configuration updates
• Refactors identity management to use Jotai atoms instead of React Context
• Adds a collaboration toggle state with UI controls in the share dialog
• Automatically enables collaboration when accessing another user's notebook

• The useIsSynced hook does not update when isCollaborationEnabled changes. If collaboration is enabled after initial render, isSynced will remain true even though the provider may not be synced yet. The isCollaborationEnabled should be added to the useEffect dependency array, and the logic should handle the state change dynamically.

export function useIsSynced() {
  const provider = useConnection();
  const [isCollaborationEnabled] = useIsCollaborationEnabled();
  const [isSynced, setIsSynced] = useState(provider.isSynced || !isCollaborationEnabled);

  useEffect(() => {
    const onSynced = () => setIsSynced(true);
    provider.on("sync", onSynced);
    return () => {
      provider.off("sync", onSynced);
    };
  }, [provider]);

  return isSynced;
