Brewfile: toggleMute and QuickMD, from their authors' taps

Neither is in homebrew-cask. That costs three things this file cannot express
on its own, so install.sh carries them: brew will not load a cask from an
unofficial tap until it is trusted, which is per machine and recorded outside
the repo; the trust is granted per cask rather than per tap, so it covers these
two files and not whatever the taps add later; and toggleMute is not notarized,
so Gatekeeper refuses it until com.apple.quarantine is cleared -- that one
attribute on that one path, not the `xattr -cr` its README asks for.

Nothing here vouches for either binary, and a third-party tap can change what
it installs between two runs. Both are deliberate exceptions, named as such.
