【需要登录】对某条需求「找他聊聊」：与发起人建立 1-1 会话并登记接洽。任何人都能接洽、人数不设上限，需求不会因被接洽而下架。幂等：重复调用只返回已有会话。
【组合链——这是关键】返回 conversationId，直接接 send_message 在该会话继续谈；开聊前可先 get_conversation_needs 一次拿全双方需求上下文。谈妥交付后双方各调一次 complete_need 完成。
【失败语义】不能接洽自己的需求 400 cannot_contact_own_need；404 need_not_found；**429 chat_quota_exhausted = 今天新开会话的额度用完了**（回复老会话不受影响），返回体自带出口，别退避重试。
