"""Normalizes a run path into its constituent parts: entity, project, and run ID.

This function processes a target string that can either be a URL or a path-like string. It extracts the entity, project, and run ID from the target string. If the target is a URL, it parses the URL to extract these components. If the target is a path-like string, it splits the string to extract the components. The function raises a ValueError if the target string cannot be parsed into the required components.

Args:
    target (str): The target string to be normalized. This can be a URL or a path-like string.
    entity (Optional[str]): The entity name. Required if the target is a bare run ID.
    project (Optional[str]): The project name. Required if the target is a bare run ID.

Returns:
    Tuple[str, str, str]: A tuple containing the entity, project, and run ID extracted from the target string.

Raises:
    ValueError: If the target string cannot be parsed into the required components or if a bare run ID is provided without the entity and project.
