The CoreEditor project began as a small initiative and is now expanding. We should consider modularizing it to separate the business logic and enhance reusability.

To begin:

• Create a mono repo (or "workspace") for CoreEditor.
• Keep CoreEditor/package.json as the main entry point.
• Add a CoreEditor/packages folder and relocate modularized packages there.
• Add a CoreEditor/packages/markedit-hello local package for testing purposes.
• Include CoreEditor/packages/markedit-hello in CoreEditor/package.json to test the workspace.
