Async Streaming Support: Real-time message streaming for all Claude-based steps
- Message-by-message streaming displays complete messages as they arrive from ClaudeCodeSDK
- 6 specialized stream handlers: console, simple, debug, file, buffer, and callback
- Works with all Claude step types (claude, claude_smart, claude_session, etc.)
- Progressive display of assistant responses, tool uses, and results
- Memory-efficient processing without buffering entire responses
- Full mock support for testing without API calls
- Documentation: ASYNC_STREAMING_MIGRATION_GUIDE.md and examples/STREAMING_GUIDE.md
