Implement summary generators to handle large BatchResult payloads (>256KB) in map and parallel operations, matching TypeScript SDK behavior. When results exceed checkpoint size limit, operations use ReplayChildren mode with compact JSON summaries instead of full result serialization. Key changes: - Add SummaryGenerator protocol and default implementations - Extend ParallelConfig/MapConfig with summary_generator field - Update ConcurrentExecutor to pass summary generators to child contexts - Implement replay_children logic based on payload size, not generator presence - Add test coverage for small/large payload scenarios This enables efficient handling of large concurrent operation results while maintaining deterministic replay behavior and preventing checkpoint size violations.
