Greptile Summary

This PR updates all user-facing examples, tutorials, benchmarks, and documentation to use the public EmptyTask symbol instead of the private _EmptyTask alias, following the refactor introduced in #2062.

• Six files are updated with purely mechanical renames: _EmptyTask → EmptyTask in imports, type annotations, docstrings, and inline comments.
• EmptyTask is confirmed publicly exported from nemo_curator/tasks/__init__.py, so all updated call sites are correct.

Confidence Score: 5/5

Safe to merge — all changes are mechanical renames of a private symbol to its public equivalent, confirmed exported from the tasks package.

Every change is a straightforward substitution of _EmptyTask with EmptyTask, which is verified as a public export in nemo_curator/tasks/__init__.py. No logic, runtime behaviour, or interfaces are altered.

No files require special attention.
