- Support MDM/Munki/Jamf runs where the parent process is root but
Homebrew must execute as the logged-in macOS console user.
- Keep the nested operation constrained to `HOMEBREW_BREW_FILE` so this
helper cannot become a general-purpose root command launcher.
- Share `macos_user.sh` with installer scripts so no-user and package
plist fallback behaviour cannot drift between install paths.
- Stage `macos_user.sh` for `pkgbuild` because `preinstall` needs the
resolver before the Homebrew payload has been installed.
- Allow specifying user through `/var/tmp/.homebrew_pkg_user.plist`
- Improve permission handling
- Correctly write API cache
- Add `preinstall` script to fail if we can't get a valid user
