Struct PortableBlake3ParallelCompression 

pub struct PortableBlake3ParallelCompression<const LANES: usize> { /* private fields */ }

Parallel Blake3 two-to-one compression backed by the portable auto-vectorized kernel.

The Merkle inner-node counterpart to the leaf digest PortableBlake3ParallelDigest. Every parent folds a pair of 32-byte child digests as blake3(left || right). A batch of LANES node pairs is a fixed-length batched Blake3 over 64-byte messages. Each batch runs through the shared block-compression core in one pass.

Output is bit-identical to the scalar Blake3Compression, pinned to it in tests.
