Crate shuflr_wire 

shuflr-wire/1 protocol codec — pure framing / parsing with no I/O.

Specced in docs/design/005-serve-multi-transport.md §3. This crate knows nothing about sockets, TLS, pyo3, or tokio. It turns Message values into bytes and back, with an xxh3 checksum on every non-handshake frame.

The transport (PR-33) drives this codec from a tokio::io::{AsyncReadExt, AsyncWriteExt} loop; the shuflr- client Python wheel (PR-34b) uses it from a blocking std::io loop. Both sides use the same encode/decode pair — byte-for-byte compat is pinned by the proptest round-trip harness in tests/.

Constants

MAGIC
