refactor: extract atomic_json_write helper, add 24 checkpoint tests
...
Extract the duplicated temp-file + fsync + os.replace pattern from
batch_runner.py (1 instance) and process_registry.py (2 instances) into
a shared utils.atomic_json_write() function.
Add 12 tests for atomic_json_write covering: valid JSON, parent dir
creation, overwrite, crash safety (original preserved on error), no temp
file leaks, string paths, unicode, custom indent, concurrent writes.
Add 12 tests for batch_runner checkpoint behavior covering:
_save_checkpoint (valid JSON, last_updated, overwrite, lock/no-lock,
parent dirs, no temp leaks), _load_checkpoint (missing file, existing
data, corrupt JSON), and resume logic (preserves prior progress,
different run_name starts fresh).
