Cheap for a reason worth stating: the Windows package is already a SOURCE
install - a pure-Python wheel plus a setup tool that builds a venv on the
target machine, because PyInstaller cannot cross-compile. macOS needs
nothing different. Same wheel, same setup tool, a natively built .app in
place of the .exe. No frozen engine, no 200 MB, no second packaging story.
behavision-setup already handled both platforms (Scripts vs bin, the
tasklist check guarded) and cross-compiled for darwin without a change.
The one thing that did not was its advice when Python is missing: it told
everyone to tick 'Add python.exe to PATH' on a Windows installer page.
Software that does not know which machine it is running on is software
somebody stops trusting for the rest of the session.
MAC=1 opts in, so the ordinary Windows release is unchanged.
