gh: git handoff
Commit the relevant changes, push, and open a PR (follow user instructions exactly):
- Stage what belongs together, commit with a Conventional Commits message.
- Push the current branch (create one off the default branch first if needed).
- Open a PR with
gh pr create— concise title, short what/why body. - Print the PR URL.
Keep output minimal: the PR URL on success, the exact error on failure.
