// 写一个Tampermonkey脚本
// 用在 https://aistudio.google.com/prompts/ 开头的网页
// 在页面上加一个链接，"Set Global System Prompt"
// 点击链接出现弹窗，里面有个输入框，可以输入全局系统提示词，默认为：
// Always search in English. Answer in the same language as the question.
// 这个全局系统提示词保存到本地，如果用户调整过，下次打开页面时，要保持用户调整后的内容
// 找到class名为 "system-instructions" 的节点，找到里面的textarea，把textarea里的内容改为全局系统提示词
