The Manjaro workspace job failed test-unit-ruby with "cannot load such file -- minitest". Debian vendors minitest in libruby, but Arch ships it as ruby-minitest and Fedora and CentOS Stream as rubygem-minitest, none of which ruby pulls in. ensure_ruby_present now probes `require "minitest"` and installs the distro package when the probe fails, then fails loudly if minitest is still missing.
