Rename references to the idiot

As we try to produce generic, public, and good documentation, we should move away from referring to the idiot and instead use something like dcu or devcade compute unit

在仓库中搜索对 "the idiot" 的引用，并检查文档或面向用户的内容中每个匹配的出现位置。将该术语统一替换为 "dcu" 或 "devcade compute unit"，然后确认不再存在不恰当的引用。
