Add real-time collaboration tools for GrapesJS projects.

[Tavrie]

Hey everyone;
Right now, if a website owner wants to get help with a GrapesJS project, they have to use outside tools like email or chat to coordinate with a small group of collaborators. This is clunky and makes it hard to see who did what and when.

I propose adding built-in collaboration features for 3–5 collaborators directly within the GrapesJS project dashboard. This would make things much easier and more efficient.
Here's a quick breakdown of what it could include:

1. Co-editing: Let multiple users work on the same project in real time, like in Google Docs.

2. Inline comments: Enable collaborators to leave feedback and notes directly on specific design elements or content blocks.

3. Task management: Allow the owner to create and assign simple tasks right within the project, like "update the CTA button" or "rewrite the landing page copy."

4. Version history: Give the owner a clear record of all changes and the ability to roll back if something goes wrong.

This would be a huge quality-of-life improvement for anyone using GrapesJS to build and maintain a site with a small group.
