[Enhancement] Create branch on detached Head

[esierp]

When I'm in a detached HEAD state in Git, I encounter an error when trying to create a branch from it. I can make commits while in the detached HEAD state, but these commits don't appear in the graph and subject window, indicating they're on a detached head. Additionally, I can't create a branch from these commits within the tool. However, when using another tool, I can see the commit and create a branch from it, which then becomes visible in the graph and subject window. If this occurs in a submodule, I can see the commit ID and the changes in the top-level module.

Head is now shown in the graph - which is realy fine!
I can create a branch on the detached head - which is good!
If i create a commit on the detached head, without create a branch previously. I can't create the branch over the local branches window - but with right click on commit and create a branch it works

Really great work!

I've pushed a new commit e05264e to fix the issue that users can not create branch based on detached HEAD with extra commits. You can test it from https://github.com/sourcegit-scm/sourcegit/actions/runs/10316558339

Bugfix is working like a charm!
