### Describe the improvement

When the view is in grid mode, add an extra row to display the software source (e.g., scoop, winget), as indicated by the red arrow in the image.

### Describe how this improvement could help users

This helps users determine which installation method to use in this view mode. As shown in the figure, it's currently difficult to tell which installation method was used for the two Clink packages in the first row. Adding an extra line to indicate the source (e.g., scoop, winget) would help users quickly identify the installation method.
