Phase 7: Implement Fetch path schema reconstruction framework
- Add schema reconstruction functions to convert SMQ RecordValue back to Kafka format - Implement Confluent envelope reconstruction with proper schema metadata - Add Kafka record batch creation for schematized messages - Include topic-based schema detection and metadata retrieval - Add comprehensive round-trip testing for Avro schema reconstruction - Fix envelope parsing to avoid Protobuf interference with Avro messages - Prepare foundation for full SeaweedMQ integration in Phase 8 This enables the Kafka Gateway to reconstruct original message formats on Fetch.
