fix(static): aibox Web客户端适配中断机制(Ctrl+C可靠停止)

问题（与BotOps v1.3修复一致）：
- interrupt_ack只显示系统消息，没有立即收尾前端状态
- 思考区域一直停留在"💭 思考中..."状态（服务端中断不发reasoning_end）
- AI状态未重置，残留reasoning片段可能重新创建思考区域

修复：
- 新增abortReasoning()函数：中断时更新思考区域标签为"🛑 思考已中断"（保留已展示内容）
- appendReasoning()增加aiActive===false检查，中断后丢弃残留片段
- interrupt_ack处理改为：先abortReasoning()更新思考区域，再finishAi()收尾AI状态，最后显示通知
- 中断后残留chunk/reasoning/complete均被安全忽略（appendAi已有aiActive检查，finishAi幂等）
