def breadcrumbs(request):

    Generates a breadcrumb trail for the given request path.

    The function processes the request's path, splits it into individual
    segments, and creates a list of breadcrumb entries, each representing
    a segment of the path. Each breadcrumb entry consists of a 'name'
    (key) and its associated 'url' (key). The 'name' is a title-cased
    representation of the path segment, and the 'url' is the cumulative URL
    path leading to that segment.

    :param request: The request object containing the path to be processed.
    :type request: Any
    :return: A dictionary containing a list of breadcrumbs, where each
        breadcrumb is represented by a dictionary with 'name' and 'url'.
