"""Installer repair/upgrade reruns detect a built desktop app on every arch (#94703).

electron-builder names the unpacked output ``<os>-unpacked`` on x64 but
``<os>-<arch>-unpacked`` elsewhere (``linux-arm64-unpacked``,
``win-arm64-unpacked``; macOS uses ``mac-arm64``). install.sh and install.ps1
only knew the x64 names, so a rerun on an ARM64 desktop install skipped the
desktop rebuild and left a bundle built from the previous code.
