Uncommit

Undo the last commit on the current branch, leaving the changed files as unstaged modifications in the working directory.

Instructions

1. Run git log --oneline -1 to show the user which commit will be undone.
2. Run git reset HEAD~1 to undo the last commit (mixed reset — changes become unstaged).
3. Run git status to show the resulting working directory state.
4. Report the result to the user.
