Command-line overrides doesn't work for CLI

[linhaowei1]

It seems that

        if args.api_base:
            config.llm.api_base = args.api_base
            print(f"Using API base: {config.llm.api_base}")

        if args.primary_model:
            config.llm.primary_model = args.primary_model
            print(f"Using primary model: {config.llm.primary_model}")

        if args.secondary_model:
            config.llm.secondary_model = args.secondary_model
            print(f"Using secondary model: {config.llm.secondary_model}")

The current code in cli.py doesn't correctly update the list of models. Although the primary_model and secondary_model are set from command-line arguments, this happens after the config object has already initialized its models list with default values in the __post_init__() method. This means the application will always use the default models instead of the ones specified by the user.

I will clean up the cli, but you can use a config yaml to set all these. We do not have a primary and secondary model we allow a list with weights.
