Module java_migration 

Java/Spring migration contract for legacy Hazelcast consumers.

The real Java artifacts live outside the Cargo workspace, but their public behavior is anchored here so the Rust protocol gate can enforce stable error mapping, safe codec registration, and fail-loud unsupported Hazelcast APIs.
