* swapCalc.test.js — 前端计算逻辑单元测试

* ============================================================================
|
||
* 双重目的：
|
||
* 1) 回归守卫：锁定 4 个曾出 bug 的纯函数（dcf649f2 / 20ea93d8 / 3c5f25a5 / f873239a）
|
||
* 2) 交叉校验：用 8 个场景（FC_001~FC_008）对齐 C# FrontendCalcCharacterizationTest 金标准，
|
||
* 一旦 JS 公式与后端 FrontendCalcReference 分叉，测试即红。
|
||
*
|
||
* 运行：cd YLErpWeb/fe-tests && npm i && npm test
