# pixi clones git dependencies (e.g. vinca) into its cache, which setup-pixi saves.
# git's background auto-maintenance can leave a lock file in such a clone ("hardlink
# different from source at .../commit-graph-chain.lock"), which then breaks every
# later run restoring that cache. This step runs before Setup pixi, so it also covers
# the build script.
