Summary

While looking into some performance issues with larger repositories, I noticed that we call the method snapshot inside the commit details & ref label render function, that clones the whole snapshot even though we only need to know the branch name. So we don't have to own/know the whole snapshot/state, so we can avoid doing this by using the deref reference of the repository snapshot.

Testing

I tested that it still shows the right branch, which it should. Because we still point to the same value, but we just skip a clone per ref label that is inside the git graph :).

Self-review

• I've reviewed my diff for quality, security, reliability, and performance.
• UI changes follow the checklist.
• Tests cover the new or changed behavior.

Release Notes:

• Improved Git graph rendering performance by avoiding unnecessary repository state clones.
