Module codec 

Canonical encoding and decoding of mnem objects.

Two codecs are exposed:

• dagcbor - the canonical storage format. Byte-exact deterministic per SPEC §3. Every content hash in mnem is computed over DAG-CBOR output.
• dagjson - a debug / inspection format. Never hashed, never written to the object store as canonical content. Useful for mnem cat-file --json and error messages.

The most common operation is dagcbor::hash_to_cid which encodes a value to canonical CBOR and computes its content-addressed CID.
