Crate exo_messaging 

EXOCHAIN constitutional trust fabric — end-to-end encrypted messaging.

This crate provides:

• Key exchange (kex) — X25519 Diffie-Hellman with caller-supplied key material
• Message envelopes (envelope) — Encrypted message container types
• Compose & lock (compose) — Sender-side: encrypt + sign → Lock & Send
• Open & verify (open) — Recipient-side: decrypt + verify signature
• Death triggers (death_trigger) — Afterlife message release state machine
