A bare `chsh -s /usr/bin/zsh` authenticates the calling user through PAM and
prompts "Password:", stalling an unattended install right after oh-my-zsh.
Run it via `sudo chsh ... "$(whoami)"` so it uses the passwordless setup sudo
rule and completes silently (also more reliable: it targets the account
explicitly rather than relying on the ambient user).
