Autorun script so the same drunkendotfiles deploy gives each host a
distinctive nick without per-host config hand-edits. Trims FQDNs to
the short hostname before composing. Static 'nick = "`"' in
config stays as a fallback if the script ever fails to load.
Tracks shell configs (zsh/bash), vim, tmux, irssi, fonts, themes,
and ~/.local/bin scripts. Sensitive files (.ssh, .gnupg, history,
credentials) and large app data are excluded via .gitignore.
