feat(zsh): Replace emacs-mode up/down pattern search

- Replaces emacs-mode experience: type 'git submodule add', press up-arrow to begin
  browsing history that starts with that string. zsh only uses the first
  word.
- This replacement: type the partial (multi-word) command, press CTRL-R (ins mode)
  or '/' (cmd mode), then use CTRL-K/J to browse matches.
