Default branch: !`git symbolic-ref refs/remotes/origin/HEAD --short 2>/dev/null | sed 's|.*/||' || echo main` Report only what changed. Locate; don't fix. If no URL in `$ARGUMENTS`, ask for one. Parse `$ARGUMENTS`: strip `--branch <name>` if present → branch mode. If `--branch` has no value, use the default branch above.
