feat: add branch selection prompt in setup process

- Introduced a new promptBranch function to allow users to select between 'main' and 'nightly' branches during the setup.
- Updated cloneAndBuild function to use the selected branch for cloning and pulling updates, enhancing flexibility in repository management.
- Implemented logic to switch branches if the current branch differs from the selected one, ensuring the correct branch is used.
