While investigating this issue, I found that the root cause appears to be related to UV's handling of packages that provide the same executable.
just and rust-just are different UV packages, but both install just.exe.
When a user has previously installed just manually and IDEasy later installs rust-just, UV aborts with an executable conflict unless --force is used.
This seems related to the behavior discussed in UV issue astral-sh/uv#18854 .

I tested this locally and ide installs just successfully even after having it installed earlier using uv. Adding the --force flag seems to fix the problem, as also hinted in the error output.

I think it's worth discussing however if --force should be in Just or in UvBasedCommandlet. I'm not sure if this problem also occurs with other uv based tools, but in that case one might consider making this solution a bit broader.

Otherwise, great work!

@JoelAdbu thanks for your PR. You fix seems clean and according test changes are obviously required. Good job 👍
Ready for merge.
