Phase 3: Add comprehensive integration tests
- Add end-to-end flow tests for Kafka OffsetCommit to SMQ storage - Test multiple consumer groups with independent offset tracking - Validate SMQ file path and format compatibility - Test error handling and edge cases (negative, zero, max offsets) - Verify offset encoding/decoding matches SMQ broker format - Ensure consumer group isolation and proper key generation
