- agent_import.dump_yaml_file now calls utils.atomic_yaml_write instead
of hand-rolling safe_dump + atomic_write_text — same temp+fsync+atomic
rename and symlink preservation, plus mode/owner preservation a
0600-secured config.yaml needs
- openclaw script: the EXDEV/EBUSY copy fallback gains copystat + target
fsync so the docstring's 'mirrors utils.atomic_replace' durability
claim is true on cross-device deployments
- trim load_yaml_file's docstring to the behavior contract
