# Windows MSYS2/pacman setup with two workarounds:
# 1. Core package updates (pacman, msys2-runtime) terminate bash.exe via taskkill - use Windows-level
# error suppression (|| ver >nul) since bash can't execute || true when forcibly killed
# 2. Mirror timeouts cause "Operation too slow" errors - use --disable-download-timeout + retry
