* test(render): add comprehensive tests for MsgPack render * test(render): make msgpack tests deterministic Decode the rendered msgpack output and assert values instead of comparing raw bytes (which can vary with map iteration order). Enable MsgpackHandle.RawToString so msgpack strings decode as Go strings. --------- Co-authored-by: AmirHossein Fallah <amirhossein.fallah@arvancloud.ir>
