Build rank-local and Scheduler-native configs using vLLM utilities.
indexes_kv_by_block_stride carries the native backend requirement that 0.29 removed from AttentionSpec. Every diffusion backend in tree declares False, so the default reproduces current behaviour; a caller that learns otherwise from its workers passes True here and the block-outermost layout propagates to every rank-local config.
