Sync popup need not warn when no changes to commit.

I was on my primary branch and had no uncommitted work.  Never the less, when I went to "Sync" to pull in the latest changes, I was presented with this warning:

<img width="792" height="320" alt="Image" src="https://github.com/user-attachments/assets/7d74e914-dd41-4cfd-963b-811da0036b0d" />

If there are not files to commit, then the warning need not be presented to the end user.
