Drops both git_deploy clones (ohmyzsh, zsh-autosuggestions), the chown
action, the bw.zsh-theme, and the plugin directories. /etc/zsh/zprofile
now embeds a compact prompt mirroring the old theme's colors (no git
segment), sources zsh-autosuggestions from the new apt package, and
binds prefix-history search on the arrow keys.
Per-user ~/.zshrc is kept as a one-line marker so zsh-newuser-install
doesn't fire when ckn logs in.
Leftover /etc/zsh/oh-my-zsh/ trees aren't removed automatically — clean
once with `bw run linux 'rm -rf /etc/zsh/oh-my-zsh'` after the next
fleet-wide apply.
