Implements Task 8. play_backup.yml ensures the local dir then includes backup.yml,
which runs /export + /system backup save and pulls both over SCP (net_get).
Binary .backup is gitignored (may contain secrets); export.rsc is committed.
Verified against crs310-maker on the bench: both artifacts fetched non-empty.
