### Describe the improvement

Add custom user note (saved to local config files) to the package details and as a custom column in installed packages list

### Describe how this improvement could help users

Winget isn't a great package manager, so it doesn't preserve custom install location when updating apps and instead installs a second duplicate app. To avoid this you can disable updates for this package (if it's not available anywhere else) so that it never appears in UniGet update UI
But then it would be nice to know the reason behind this so that later when you see an app that's locked you're not wondering whether to turn it back on or leave it off (maybe you've disabled another app for another reason).

One area where this note could be added is in the package details. And another is the installed packages list so that it's immediately visible without having to open package details
