## Summary Adds client-side logic to convert a Kafka Streams topology to wire format and stash it on `StreamsRebalanceData` at `StreamThread` startup. ## File changes - **`StreamsRebalanceData`**: three new fields `wireTopologyDescription`, `memberId`, `topologyPushRequired` with setters/getters and a unit test. - **`StreamsConfig`**: new client config `topology.description.push.enabled` (boolean, default `true`). - **`TopologyDescriptionConverter`**: new internal helper that converts `TopologyDescription` to `StreamsGroupTopologyDescriptionUpdateRequestData.TopologyDescription`, with 4 unit tests covering multi-subtopology, branching, stateful processor + global store, and dynamic sink topic. - **`StreamThread.initStreamsRebalanceData`**: calls the converter at startup and stashes the result on `StreamsRebalanceData` when the config is enabled. -- This is an automated message from the Apache Git Service.
