## Summary by cubic
Fixes incorrect Git committer identity when creating commits with native
Git. We now set user.name and user.email via -c flags so both author and
committer match app settings.

- **Bug Fixes**
- Added withGitAuthor to prepend -c user.name and -c user.email to git
args.
- Updated gitCommit to use withGitAuthor instead of --author (works with
--amend).
