Module body 

L2 block body: application data and standardized emissions.

The body owns calculation of its BODY_ROOT by composing the two subroots:

• DATA_ROOT: Merkle root of per-byte data item hashes.
• EMISSIONS_ROOT: Merkle root of per-emission hashes.

Both collections are sorted by their hash for determinism (sorting is done on a local copy so calculate_* methods do not mutate the body).
