**Add type hints and Google-style docstring for `generate_avatar_cmd`.**

This public command function lacks typed parameters and the required Args, Returns, Cost, and Example sections in its docstring. Per coding guidelines, all public methods must include type hints and Google-style docstrings.

```
In `@packages/core/ai_content_pipeline/ai_content_pipeline/cli/commands/media.py`
around lines 38 - 42, The public CLI function generate_avatar_cmd is missing
type hints and a Google-style docstring; add explicit type annotations for all
parameters (e.g., ctx: click.Context, image_url: Optional[str], audio_url:
Optional[str], text: Optional[str], video_url: Optional[str], reference_images:
Optional[List[str]], prompt: Optional[str], model: str, duration: int,
aspect_ratio: str, save_json: bool) and a return type (-> None), and replace the
current short docstring with a Google-style docstring that includes Args,
Returns, Cost, and Example sections describing each parameter, what the function
returns (None), estimated cost, and a usage example; keep references to ctx.obj
(e.g., ctx.obj["output"]) in the description where relevant.
