A bare version request lets uv pick an emulated x86_64 CPython on
Windows arm64 hosts ("support for the native architecture (aarch64) is
not yet mature"). The bootstrap interpreter then ran as win-amd64.
Request cpython-<minor>-windows-<arch>-none from the machine
architecture the scripts already detect, in install.ps1,
setup-hermes.ps1 and setup-hermes.sh (win32 only; POSIX keeps the bare
version so uv still picks the right libc variant).
