Content-addressable serialization for CJC values.

cjc-snap provides deterministic binary encoding of Value types with SHA-256 content hashing. Zero external dependencies -- the SHA-256 implementation is hand-rolled following FIPS 180-4.

Overview

  Value ──snap_encode──> bytes ──sha256──> hash
         ◄──snap_decode──

The high-level API is snap() / restore():

let blob = cjc_snap::snap(&value);
let restored = cjc_snap::restore(&blob).unwrap();
