docs: LangGraph 워크플로우 session 처리 및 조건부 엣지 추가

Browse Source 
- ColdmailState에서 session 제거 (직렬화 불가)
- 각 노드에서 async with aiohttp.ClientSession() 개별 생성
- route_after_filter 함수 추가
- add_conditional_edges로 filter → END or process 분기
- process 노드에서 for 루프로 여러 이메일 처리
- try-except로 IR 실패 시 continue 명시
- 96줄 유지
