`netssh hook install` and the setup wizard now write the same marked
`# >>> netssh >>>` block as install.sh and replace unmarked entries of
older versions instead of appending duplicates. Uninstall shares the
legacy patterns with the installer (eval/alias/source variants).
For zsh the block adds ~/.zfunc to fpath and calls compdef, so
completion also works when compinit already ran earlier in .zshrc,
e.g. with oh-my-zsh. The installer reports which completion it set up
per shell and how to reset ~/.zcompdump.
