zshrc: find Homebrew's completions on the prefix this machine uses fpath carried /usr/local/share/zsh-completions, which is wrong twice over: Apple Silicon puts Homebrew under /opt/homebrew, and formulae install their completions into share/zsh/site-functions, not the share/zsh-completions of the formula by that name. The directory existed on neither Mac, so _brew, _bat, _deno and the rest have been missing all along -- silently, since a missing fpath entry says nothing. All four candidates are probed now, HOMEBREW_PREFIX first where a machine exports it. No `brew --prefix`: that forks on every interactive shell, and this file already pays for one of those further down.
