ek-ui 0.4.5

//! `ek-ui` 主程序:参数形态接线(界面零配置口径,2026-10-17 用户定盘)。
//!
//! - 无参:demo 窗(dm + oms + ui;网关经运维窗激活);
//! - `--pick`:选窗启动(S1c;选的是 station 工厂表里装什么 —— 结构面);
//! - `--from <清单>`:launcher 协议(BD-UI-14;与 ek-station 同语义);
//! - `--ready-file <标记>`:launcher 就绪协议伴随旗;
//! - 未知参数 usage exit 2。
//!
//! 纪律:ek-ui 不读任何配置文件(零配置口径,见 DESIGN BD-UI-19;需配置的
//! 插件其配置面归插件自身);插件结构只由 `--from` 清单或 demo 缺省决定,
//! ui 插件缺省自动补入。
