Bug: Prune tag duplicates

[admbeck]

Is your feature request related to a problem? Please describe.
During manual tagging, tag duplicates may appear that I fail to notice at first or even second glance. These are not aliases, but literal duplicates, such as two instances of "original" or a specific eye color.

Describe the solution you'd like
I would like the application to automatically check for any duplicate tags during the tagging process. If duplicates are found, the system should prevent the user from saving the image until the duplicates are resolved. Ideally, the application would also highlight or point out which tags are duplicated, making it easier for the user to correct the issue.

Describe alternatives you've considered
Manual Checking: Manually reviewing tags to spot duplicates before saving. This is time-consuming and prone to human error.
Post-Tagging Review: Implementing a secondary review step where duplicates are flagged after saving. I even had to made a python script to prune duplicates, there were so many of them.

Huh. In theory, those should've been grabbed by both the autofixer and the tag text field.

Can you show it in action with an image that will be added?

The issue exists on 1.5.2. I tested it with 1.6.0-pr and I am yet to encounter duplicates. This is screenshot on 1.5.2. "solo" tag is duplicated


Opening this image in 1.6.0-pr and saving it again removed duplicate tags for this image.
