- lib_py/registry_format.py: a pure, idempotent migrate() drops
kill_command/start_command and rebuilds attach_command on every row
(stopped/terminated included) and sets the top-level registry_format key.
- atomic_dump_yaml migrates an older registry under its lock, before the
caller's mutation, and then rewrites the YAML as well as the DB (the YAML
write is otherwise skipped when only fields change). load_state_json stays
read-only. New registries are written with the current version.
- Entry point for #72: `python -m lib_py.registry_format --yaml <path>` runs
the migration through the writer and prints
`registry-format: <from> -> <to>, rows changed: <n>`.
