updater scans installed apps, determines where each app should be checked (Sparkle, Homebrew casks/formulae, Mac App Store via mas, GitHub Releases, and macOS system updates), then runs source specific update actions from the terminal. It also has an interactive TUI (run `updater` with no args).

A few commands:

updater check updater update --all updater update "1Password"

Would love feedback, especially on reliability and edge cases.
