Add 'extra' key to example specifications

Pull request overview

This PR attempts to add defensive code to ensure the extra dictionary exists in example specifications before setting the task_name key within it. The change prevents a potential KeyError when accessing example_spec["extra"]["task_name"].

Key Changes:

• Add a check to initialize example_spec["extra"] as an empty dictionary if it doesn't exist before setting task_name

This code assumes example_spec is always a dictionary, but according to the type hint on line 378, example_spec can be either a dict or a DesignInputSpecification object. When it's a DesignInputSpecification object:

1. The 'extra' not in example_spec check will fail because Pydantic models don't support the in operator for checking attributes
2. Dictionary-style access example_spec["extra"] will raise an error because Pydantic models require attribute access (example_spec.extra)

To handle both cases, consider:

# Handle both dict and DesignInputSpecification types
if isinstance(example_spec, dict):
    if 'extra' not in example_spec:
        example_spec["extra"] = {}
    example_spec["extra"]["task_name"] = prefix
else:
    # DesignInputSpecification has extra field with default_factory=dict
    if example_spec.extra is None:
        example_spec.extra = {}
    example_spec.extra["task_name"] = prefix

Alternatively, if all DesignInputSpecification objects should have the extra field initialized (which they do by default), you could simplify by converting to dict first or using attribute access for Pydantic objects.
