feat(nyai): 更新规范+导出过滤 — 防降级安装(version点分比较,新版<已装拒装/缺失拒装,先解 staging 再替换) + 导出两层模式(黑名单 find+tar -T 排除 *.pre_*/.bak_*/logs//*.log/.DS_Store 且去 ./ 前缀 / 白名单 export_files 逐项安全校验) + 导出体检(app.json合法+exec存在可执行) + install/upgrade 成功后自清 .bak_<pid> + os.meow.* 签名提示与 2A 验签挂点注释 (agent-180)
nyai e5514929→新值见 fw_content.conf; 宿主 17/17 场景全过(首装/升/同版/降级拒/无版本拒/黑白名单/体检/round-trip); cmd_upgrade 同步加防降级门禁(堵绕过) 出入: 版本严格解析(1.2.3-beta 判不可比拒装, 与定案一致); busybox tar --exclude 未真机验证→用 find|tar -T 兜底
