📄 Description

修复了在 K8s/Docker 环境中运行时出现的错误：
File "/usr/local/lib/python3.12/site-packages/twisted/mail/imap4.py", line 1685, in __cbManualSearch
lastSequenceId = result and result[-1][0]
TypeError: 'generator' object is not subscriptable

问题原因：

fetch 方法返回了生成器对象
Twisted IMAP4 库在处理 SEARCH 命令时需要对结果进行索引访问
生成器不支持索引操作

解决方案：

将 fetch 方法的返回值从生成器改为列表
保持 fetchGenerator 方法的分批获取逻辑（batch_size=20）
确保内存占用可控的同时支持所有 IMAP 操作
