Module crypto 

Crypto primitives — thin wrappers over reviewed crates.

Supported:

• ed25519 signing / verifying (via ed25519-dalek).
• SHA-256 and BLAKE3 hashing.

Post-quantum ML-DSA is a Phase 3+ addition and is reserved in the SignatureEnvelope schema today. No custom crypto is introduced in this module — everything is a thin adapter.
