morph-da-codec

Morph DA zstd decoder shared by Rust zkVM guest code and Go node code.(There will be encoder in the future)

Semantics

• input payload omits zstd magic bytes;
• decoder prepends 28 b5 2f fd internally;
• only the first complete zstd frame is decoded;
• bytes after the first frame are ignored;
• first frame content size is required and validated.
