The macOS CI artifact is an unsigned zipped ILSpy.app; the signed
distribution channel is a dmg the release manager creates offline with
create-dmg.ps1 (codesign and notarization stay optional parameters, so
no signing secrets ever live in CI). Distribution via Homebrew uses a
tap repository holding only a cask file that points at the dmg attached
to the GitHub release; the cask template and per-release update steps
are documented next to the scripts.
