fix: switch branches before deletion in abandoned branch scriptv0.8.2

- Add branch switching logic to prevent "refusing to delete current branch" error
- Check if we're on the branch to be deleted and switch to main/master first
- Skip deletion if no main/master branch exists to switch to
- Bump version to 0.8.2
