- schemas/steward.py：StewardPlanResponse 新增 suggested_prompts 字段 - steward_planner.py：新增 STEWARD_BUSINESS_SIGNAL_KEYWORDS 与 _is_business_irrelevant_input 守卫，在 build_plan 入口前置； 新增 _build_off_topic_plan 构造 plan_status=off_topic 的引导计划 - steward_intent_agent.py：system prompt 追加业务无关约束 - test_steward_planner.py：覆盖 123/你好/纯标点走 off_topic， 并验证正常业务输入不受守卫影响
