    """Configuration for the app.

    Attributes:
        llms: Dictionary mapping LLM names to their configurations.
            The default configuration is stored under the 'llm' key.
        agents: Dictionary mapping agent names to their configurations.
            The default configuration is stored under the 'agent' key.
        default_agent: Name of the default agent to use.
        sandbox: Sandbox configuration settings.
        runtime: Runtime environment identifier.
        file_store: Type of file store to use.
        file_store_path: Path to the file store.
        save_trajectory_path: Either a folder path to store trajectories with auto-generated filenames, or a designated trajectory file path.
        workspace_base: Base path for the workspace. Defaults to `./workspace` as absolute path.
        workspace_mount_path: Path to mount the workspace. Defaults to `workspace_base`.
        workspace_mount_path_in_sandbox: Path to mount the workspace in sandbox. Defaults to `/workspace`.
        workspace_mount_rewrite: Path to rewrite the workspace mount path.
        cache_dir: Path to cache directory. Defaults to `/tmp/cache`.
        run_as_openhands: Whether to run as openhands.
        max_iterations: Maximum number of iterations allowed.
        max_budget_per_task: Maximum budget per task, agent stops if exceeded.
        e2b_api_key: E2B API key.
        disable_color: Whether to disable terminal colors. For terminals that don't support color.
        debug: Whether to enable debugging mode.
        file_uploads_max_file_size_mb: Maximum file upload size in MB. `0` means unlimited.
        file_uploads_restrict_file_types: Whether to restrict upload file types.
        file_uploads_allowed_extensions: Allowed file extensions. `['.*']` allows all.
        cli_multiline_input: Whether to enable multiline input in CLI. When disabled,
            input is read line by line. When enabled, input continues until /exit command.
