name: Installer tests

# scripts/install.ps1's PowerShell tests. They exercise the installer as a real
# subprocess, and every path contract they assert (8.3 short-name aliases,
# Git Bash layouts, provider-cmdlet behavior) is Windows-specific — so they need
# a Windows runner. Before this workflow existed the files were in the tree but
# nothing ever ran them.
