Add real LangGraph workflow implementation

- Proper StateGraph with compiled nodes - Conditional edges for writing iteration - Checkpoint memory for resumability - Structured state with Pydantic - Node_validate for cross-stage validation - Writing loop with iterate/next logic - Full end-to-end workflow This is the rigorous LangGraph integration.
