fix: add git safe.directory for containerized CI with persistent cache

When using persistent cargo cache mounted from host directory, the container
user differs from the directory owner, causing git "dubious ownership" error.
This fix adds `git config --global --add safe.directory '*'` before cargo
commands in containerized jobs.
