misc tweaks: skhd bnpf bindings, neovim/doom/fish fixes

- skhd: remap window nav/move/resize/stack from hjkl to Emacs-style bnpf;
  remap fullscreen/zoom to m, borders to o, prev/next space to [/];
  add super-z to open emacsclient
- neovim: fix catppuccin integration key (neo_tree -> neotree) so init
  loads without the "module not found" traceback
- doom: disable lispy/objed/parinfer modules
- fish: add ~/.bun/bin to PATH
