oh-my-zsh's install script, even with RUNZSH=no/CHSH=no, still prompts
"Do you want to overwrite it with the Oh My Zsh template? [Y/n]" in interactive
mode — which hangs an unattended/answerfile install at the shell-setup module.
Pass --unattended to skip all prompts, and KEEP_ZSHRC=yes so it preserves the
dotfiles ~/.zshrc symlink (created earlier in this module) instead of replacing
it with the oh-my-zsh template.
