Dotfiles Setup

Puts machine configuration under version control and makes it restorable on the next Mac — without the classic failure modes: clobbering live config during adopt/deploy, and committing secrets on day one.

When NOT to use

• The content of .zshrc → zsh-setup; of .gitconfig → git-ssh-identity
• Generating/refreshing the Brewfile → homebrew-setup (this skill only tracks that file)
• Whole-machine setup → macos-dev-setup
• Backups of data → Time Machine, out of scope
