Add possibility to generate signed commits

I tested the tool for the first time today and I found it incredible and very practical! I just have to thank everyone involved!

Well, in this test I realized that the tool generated a commit with my name, but without any signature.

Would it be possible to integrate it with Github to generate the signature automatically? (This already happens in codespaces, for example)

I agree. This change is essential for some actions that require signed commits to be merged.

Agree; we have a requirement for all commits to be signed. It would be helpful to have the tool sign the commits just as if making the changes in github.com, etc.

I just hit this as well, I have signed commits required on my repo and was messing around with copilot workspaces to generate unit tests. I had copilot create a PR, then I made some additional changes. My commit is verified but the original copilot one isn't, and github won't let me merge.
