Consolidate Scripts

We should combine some of these scripts that have overlapping goals. One example seems to be the `chat` and the `chat-emails`. There could be others that I still need to look into.

Note: We do not want to achieve "DRY" goals. We treat these scripts as one-offs and need not spend any time maintaining code that "looks" good.

Code logic duplication is acceptable. We never want to create any cross-dependencies to avoid having to maintain these scripts as a whole.

首先在仓库中定位 `chat` 和 `chat-emails` 脚本，并比较它们的目标和实现。检查其他脚本是否存在类似的重叠，然后定义一个整合范围，在保留它们一次性使用方式的同时避免跨依赖。完成的标准是：约定的重叠脚本已完成整合，且未引入共享的维护依赖。
