Describe the improvement

At the top of the Live Output window for an update, note the currently installed version. For example:

Package update operation for Package=Brave.Brave Version=135.1.77.97 with Manager=Winget

Or more clearly with both versions in one place (rather than having to spot both version strings in different positions within the log):

Package update operation for Package=Brave.Brave with Manager=Winget from Version=135.1.77.97 -> 135.1.77.100

Describe how this improvement could help users

Once a program has been downloaded and installed it is removed from the list of available updates which is the only place which displays a program's currently installed version. Having this info written at the top of the Live Output would let you easily check which version an update was from, not only to which version it was to.

This would be helpful because not all (or perhaps only WinGet doesn't?) show the original version which is being updated (for example, Scoop shows within its output brave: 135.1.77.97 -> 135.1.77.100).

UniGetUI could ensure that this info is always present regardless of package manager used by adding the suggested from-to text at the top of each operation log.
