Subject: fix(zsh): guard compdef on target command being installed
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On minimal hosts (remote-dev VM, fresh container) several of the
`compdef alias=target` lines fail at login with messages like:

    compdef: unknown command or service: just
    compdef: unknown command or service: systemctl
    compdef: unknown command or service: lsd

— because zsh has no `_just`/`_systemctl`/`_lsd` completion function
loaded when the binary isn't on the system. Wrap each call in a small
helper that checks $commands[<target>] first so absent tools just
silently skip their alias completion instead of spamming the prompt.
