dig-message 0.5.1

The DIG Network generic base message protocol: the byte-deterministic Chia-Streamable envelope + InnerMessage, length-framed size-bounded framing, additive compression (raw + zstd, decompression-bomb guarded), and the extensible message-type registry that every directed (1:1 / group) e2e-sealed peer message rides.

# dig-message — the DIG Network generic base message protocol.
#
# ONE structured, typed, streamable, e2e-sealed envelope that every DIRECTED (1:1 / group) peer-to-peer
# message rides. This crate is the envelope + framing + compression + type-registry + streaming + seal
# contract; downstream message TYPES (dig-chat, dig-email, dig-video-chat, peer-RPC) register into it.
#
# WU1 (this milestone) ships the CRYPTO-FREE foundation: the byte-deterministic Chia-Streamable
# envelope + InnerMessage, the length-framed size-bounded codec, the compression layer (raw + zstd
# with the decompression-bomb guard), and the KAT harness. The seal (DHKEM-over-G1) and the BLS
# sender-signature/verify are WU2; the streaming state machine is WU4 — their FIELDS are present here
# as placeholders so the wire shape is final.
