airline#themes#cyberqueer#palette was undefined because the theme file was
being copied under the wrong name (cyberqueer-airline.vim instead of
cyberqueer.vim). Fixed by adding the file at the proper rtp-relative path
nvim/autoload/airline/themes/cyberqueer.vim — picked up automatically via
the ~/.config/nvim symlink, no extra copy step needed. Removed the now-
redundant manual cp from shell-setup.sh.
