CreateTopics Protocol Compliance completed: ## Implementation - Implement handleCreateTopicsV0V1() with proper v0/v1 request parsing - Support regular array/string format (not compact) for v0/v1 - Parse topic name, partitions, replication factor, assignments, configs - Handle timeout_ms and validate_only fields correctly - Maintain existing v2+ compact format support - Wire to SeaweedMQ handler for actual topic creation ## Key Features - Full v0-v5 CreateTopics API version support - Proper error handling (TOPIC_ALREADY_EXISTS, INVALID_PARTITIONS, etc.) - Partition count validation and enforcement - Compatible with existing SeaweedMQ topic management ## Tests - Comprehensive unit tests for v0/v1/v2+ parsing - Error condition testing (duplicate topics, invalid partitions) - Multi-topic creation support - Integration tests across all API versions - Performance benchmarks for CreateTopics operations ## Verification - All protocol tests pass (v0-v5 CreateTopics) - E2E Sarama tests continue to work - Real topics created with specified partition counts - Proper error responses for edge cases Ready for Phase 3: ApiVersions matrix accuracy
