As per coding guidelines, "Write docstrings for every function using Google style format with sections for Brief summary, Args, and Returns." and "Follow PEP8, use type hints, and format with black."

In `@packages/core/ai_content_pipeline/ai_content_pipeline/registry_data.py`
around lines 19 - 21, Add explicit type hints and a Google-style docstring to
the public function register_all_models(): change its signature to include a
return type (None) and document the function using Google style with a one-line
summary, an Args section (if none, state "None"), and a Returns section
describing that it returns None; ensure the docstring follows PEP257 formatting
and the file is formatted with black/PEP8 after the change.
