Subject: [PATCH] make os mv and cp commands non interactive  (#430)

- fix(fs): handle NFS permission errors with robust fallback - Catch
PermissionError/OSError(EPERM) in atomic_move and atomic_copy -
Implement layered fallback: shutil.copyfile (content only) -> system
mv/cp - Add _perform_nfs_fallback and _system_op helpers to reduce
duplication - Set fallback logging to DEBUG to reduce spam on NFS mounts
- make os mv and cp commands non interactive (-f)
