Description
It would be really useful for proto objects to provide a deterministic hash so that it can be used for version checking/conflict detection etc.
We were recently using the HashCode() method but discovered that is not deterministic across processes because wire enums use the object reference as the hashcode.

Research direction
Start by locating the proto objects' HashCode() implementation and the wire enum hashing behavior mentioned in the issue. Determine the deterministic encoding and hashing contract needed for version checking or conflict detection, then verify that equal inputs produce the same result across processes.
