**Add type hints and Google‑style docstrings with Args, Returns, Cost, and Example sections.**

Both `list_motion_models_cmd` and `register_motion_commands` are missing type hints and complete docstrings. Per coding guidelines, all public functions must include typed signatures and full Google-style docstrings.

In `@packages/core/ai_content_pipeline/ai_content_pipeline/cli/commands/motion.py`
around lines 40 - 50, Add type hints and full Google-style docstrings to the
public CLI functions: update the signature of list_motion_models_cmd() to
include a return type (-> None) and register_motion_commands(group) to annotate
the group parameter (e.g., group: click.Group or click.core.Group) and return
type -> None; for each function add a Google-style docstring containing Args,
Returns, Cost, and Example sections describing parameters and behavior
(list_motion_models_cmd: no args, returns None, cost info, example CLI usage;
register_motion_commands: group arg, returns None, cost/example), keeping the
existing behavior (calling list_motion_models and group.add_command) and
preserving the click decorators and function names.
