FuzzNewManifestFromReader fails when the parser returns both or neither of a manifest and an error, or allocates more than a fixed multiple of its input and the decompressed data it may read, plus room for the decoder's window buffers. make test runs the seed corpus; make fuzz fuzzes for one minute. Parser bug: MaxDecompressedSize did not bound decompression; the zstd decoder decoded a payload under 128 KiB in full before the LimitReader read any of it. It now decodes only what the LimitReader reads and refuses windows over the 8 MiB mfer writes with. Seeds: a frame claiming 8 GiB, two frames together over the limit, empty frames with growing windows. Model: opus-5-5
