dimos run unitree-go2 --help crashes with Pydantic validated_data ValueError

Description

What happened?

Running uv run dimos run unitree-go2 --help on v0.0.13 crashes while generating the blueprint argument help.

The command raises a Pydantic ValueError related to calling a default factory without the required validated_data argument.

What did you expect?

Expected the command to display the available arguments/options for the unitree-go2 blueprint and exit normally without a traceback.

System

Ubuntu 24.04

Robot / Sim / Hardware

Unitree Go2

No robot connection/control was initiated. The failure occurs while running the CLI --help command.

Steps to reproduce

git checkout v0.0.13
uv sync
uv run dimos run unitree-go2 --help

Environment

• Install method: uv
• DimOS version/tag: v0.0.13
• Branch state: detached HEAD at v0.0.13

Commit can be obtained with:

git rev-parse --short HEAD

Starting DimOS

Blueprint arguments:
  Override with --option/-o module.field=value.
  Nested config paths use dotted names, e.g. module.nested.field=value.

Uncaught exception occurred

Traceback:
  dimos/robot/cli/dimos.py:365 in run
    print(arg_help(blueprint.config(), blueprint))

  dimos/robot/cli/dimos.py:194 in arg_help

    return info.get_default(call_default_factory=True)

  pydantic/fields.py:741 in get_default
    raise ValueError(...)

ValueError: The default factory requires the 'validated_data' argument, which
was not provided when calling 'get_default'.

Additional context: uv run dimos list succeeds and correctly lists the built-in blueprints, including unitree-go2.

Start with dimos/robot/cli/dimos.py, especially run, arg_help, and _field_default, then reproduce with uv run dimos run unitree-go2 --help at v0.0.13. Inspect how the Pydantic field default is requested and verify that blueprint argument help displays normally without the validated_data ValueError or traceback.
