✨ Handle Workspace Root Change

### Description

Handling the event where the root of the project is moved or deleted should be handled gracefully. Right now we have a TODO comment in the directory events to handle this.

What should happen when the root is moved:
- Prompt the user with a panel that covers the workspace and offer two options
- Re-locate the workspace - user selects a directory and we re-identify the current workspace to the user-specified path.
- Close the workspace - close the workspace and remove it from recently opened, etc.
