Add macOS system preferences and fix package installations

- Fix claude-code package name (was incorrectly listed as claude-cli)
- Remove Node.js from installer (still required by gemini-cli)
- Add macOS system preferences configuration: auto-hide Dock, show hard disks, show all file extensions, auto-empty trash after 30 days
- Add Touch ID for sudo support (artginzburg/tap/sudo-touchid)
- Add automatic Homebrew updates (every 12 hours with upgrade and cleanup)
- Add new 's' option to configure system preferences separately
