整个 TUI 的地基：位置、对齐、边框都靠它。而它算错了**不会报错** —— 表现只是菜单右边框歪一点、光标偏一列，所以每条边界都在断言里钉住。 为什么必须自己算：.Length 是 UTF-16 code unit 的个数（汉字 1 个 char、2 列）；而 $Host.UI.RawUI.LengthInBufferCells 在 PowerShell 7 上对、在 5.1 上错（实测 中文 返回 2、字体边框字符 返回 6），且不抛错 —— 这种"一边对一边错"的 API 比两边都错更危险。 表里三个边界是实测踩过的：半角片假名 U+FF61–FF9F 是 1 列（不能划进全角区）；全角拉丁 U+FF00–FF60 是 2 列；emoji 是代理对，按一个码点算。 验收：断言 8 条（含空串与控制字符）；test.ps1 9/9 全绿（5.1 与 7）。
