Lambda expressions in transform_tensor_descriptor created unique template instantiations for each capture combination. This change replaces lambdas with named functor structs to reduce instantiation count: - Add merge_sequences_functor and unpack_and_merge_sequences helper - Add convert_visible_to_hidden_id and convert_visible_ids_to_hidden_ids - Add generate_arithmetic_sequence_from_scan Build analysis shows instantiation count dropped from 388 to 32 (92% reduction).
