+/**
+ * 对比脚本：商旅 vs 吉智 金额核对
+ *
+ * 输入：一个包含「商旅」和「吉智」两个 sheet 的 Excel（即 merge_kaipiao.js 的合并结果）。
+ *
+ * 逻辑：
+ *   1. 商旅 sheet：按「结算账户」聚合，「账单总金额」相加。
+ *   2. 吉智 sheet：按「*对账单/项目名称」聚合，「*账单应收总金额」相加。
+ *      （吉智的「*对账单/项目名称」对应商旅的「结算账户」）
+ *   3. 对比两侧同一 key 的金额，找出不同：
+ *      - 仅商旅有的 key
+ *      - 仅吉智有的 key
+ *      - 两侧都有但金额不一致的 key
+ *
+ * 用法：
+ *   node compare_kaipiao.js <合并excel路径> [输出结果路径]
+ *
+ * 例如：
+ *   node compare_kaipiao.js "团队开票申请表-合并.xlsx" "对比结果.xlsx"
