add Homebrew cask so BrewBar installs via brew

The repo doubles as a Homebrew tap: brew tap accepts an explicit git
URL, so Casks/brewbar.rb here is enough — no separate homebrew-* repo.
The cask downloads the zipped Release build from the matching Forgejo
release (v<version>) and verifies it against the pinned sha256. dist/
(local release artifacts) is gitignored.

Install:
  brew tap maxsoch/brewbar https://forgejo.socheleau.fr/maxsoch/BrewBar.git
  brew install --cask --no-quarantine maxsoch/brewbar/brewbar
