The code used to install Arduino CLI, platform, and library dependencies does so by creating symlinks in the appropriate locations on the runner. The files the script gathers via clone or download, are stored in a temporary folder that is deleted when the script exits. This means the installation symlink for those files has no possible use after the script finishes.
This particular pollution of the runner's environment is resolved by also registering a call to delete on exit as each symlink is created.
