[BUG]Claude Desktop Cowork Projects: Editing project folder path does not update file access permissions

What's Wrong?

When a claude desktop Cowork project's folder path is changed via "Edit details" (e.g. after renaming or reorganizing the folder structure on disk), the file access permission entry still points to the original path. On every subsequent task start, Claude reports that the old path no longer exists and prompts the user to grant permission for the new path. This repeats every time — the permission is never persisted for the updated path.

What Should Happen?

When the project folder path is updated via "Edit details", the file access permission should be updated atomically to reflect the new path. The user should not be prompted to re-grant folder access on every subsequent task start.

Steps to Reproduce

1. Create a new Cowork project with folder %USERPROFILE%\Projekte\hugo
2. Outside of Claude Desktop, rename %USERPROFILE%\Projekte\hugo to %USERPROFILE%\Projekte\otto
3. Create a new directory %USERPROFILE%\Projekte\carmen
4. Move directory otto into carmen, resulting in %USERPROFILE%\Projekte\carmen\otto
5. In Claude Desktop, open the project and edit its folder path via project details to point to %USERPROFILE%\Projekte\carmen\otto
6. Start a new task in the project
7. Observe: Claude reports that the original path (%USERPROFILE%\Projekte\hugo) no longer exists and asks whether to grant permission for the new path
8. Grant permission — task runs successfully
9. Start another task — same permission prompt reappears; the updated path is never saved to the permission configuration
