核心是确认「改配置而不弄乱文件」这件事成立：新增一路入站之后，其余 52 行逐字节不变。 搬进来的改写引擎用默认输出参数时会重排整个文件——行尾注释的对齐空格消失、流式数组被加上内边距—— 连根本没改动的段落也一起波及。不修的话「改一处只动一处」这个承诺直接落空，所以关掉了它的自动排版， 并在写回之后补了一步逐行还原。

/**
|
|
* 往返验证：读一份真实配置 → 改一处 → 写回，看未改动的部分保住了多少。
|
|
*
|
|
* 这是整个项目最先要回答的问题。如果写回之后文件面目全非，界面做得再好也没人敢用。
|
|
*
|
|
* 用法：
|
|
* bun run scripts/roundtrip.ts <源配置> <输出目录>
|
|
*
|
|
* 产出三个文件，各对应一种改动，再用 git diff --no-index 跟源文件比对。
