**Add type hints and Google-style docstrings for all public commands in this module.**

All public command functions (`list_models_cmd`, `setup_cmd`, `generate_image_cmd`, `create_video_cmd`, `run_chain_cmd`, `create_examples_cmd`) currently have only minimal one-line docstrings with no return type hints. Per coding guidelines, they must include return type hints and comprehensive docstrings with Args, Returns, Cost, and Example sections in Google style format.

<summary>Example for list_models_cmd</summary>

```diff
`@click.command`("list-models")
`@click.pass_context`
-def list_models_cmd(ctx):
-    """List all available models."""
+def list_models_cmd(ctx) -> None:
+    """List all available models.
+
+    Args:
+        ctx: Click context.
+
+    Returns:
+        None.
+
+    Cost:
+        None (read-only operation).
+
+    Example:
+        aicp pipeline list-models
+    """

In
`@packages/core/ai_content_pipeline/ai_content_pipeline/cli/commands/pipeline.py`
around lines 28 - 65, Add Google-style docstrings and explicit return type hints
(-> None) to every public click command function in this module:
list_models_cmd, setup_cmd, generate_image_cmd, create_video_cmd, run_chain_cmd,
and create_examples_cmd. For each function replace the terse one-line docstring
with a multi-line Google-style docstring containing at least: Args (describe ctx
and other params), Returns (-> None), Cost (estimate or "Low/Medium/High"), and
Example (usage snippet); also add the Python type hint for ctx as click.Context
(or Context) and a return annotation of None on the function signature. Ensure
the docstrings are placed immediately under each def and follow Google style
formatting consistently across all listed functions.
