Engine Core Async scheduling + Pipeline Parallelism: `--async-scheduling` now works with pipeline parallelism (#32359). Mamba prefix caching: Block-aligned prefix caching for Mamba/hybrid models with `--enable-prefix-caching --mamba-cache-mode align`. Achieves ~2x speedup by caching Mamba states directly (#30877). Session-based streaming input: New incremental input support for interactive workloads like ASR. Accepts async generators producing `StreamingInput` objects while maintaining…
