Possibility to copy package name

Possibility to copy package name would be a handy feature when looking for packages that might cause problems.

**Right Click > Copy package name**, or when selecting a package in the GUI automatic copy of the package name.

Look for the GUI code handling package selection and right-click context menus. The package name is likely displayed in a list or table view; add a 'Copy package name' menu item that copies the selected package's identifier to the clipboard. Test by running the GUI, selecting a package, and verifying the copy action works.
