decompress_chunk_exact_with decodes a chunk into a DecodeScratch the caller keeps between chunks, instead of a new Vec per chunk and per filter stage. Deflate inflates into a kept buffer with a reset (not rebuilt) inflater, shuffle interleaves into the other buffer, and Fletcher32 checks and drops its checksum in place (on the stored bytes when it is the first filter undone). Other filters go through the registry as before. Output and errors are those of decompress_chunk_exact; a unit test checks that for every pipeline shape and filter mask with one reused scratch.
