caoxiaozhu e9d7c56d5b feat(server): 会话上下文保留(LLM 历史 + 确定性兜底双保险)
解决用户删除草稿后说'再提交'丢失上下文的问题:

- steward.py 新增 _inject_recent_conversation_history:build_plan 前读最近 10 条对话注入 context_json
- steward_intent_agent.py 的 _build_messages 把 recent_history 暴露给模型,system prompt 加确认类话术引导
- 新建 steward_context_resume.py:should_resume_recent_task 检测'再提交'类话术 + state 有可恢复 flow,attach_resumed_task 从 state 恢复 task
- 两个 plan 入口(/plans 和 /plans/stream)都已接入双保险
- 后端 67 passed,端到端验证'上海出差→再提交'成功恢复 task
