[Bug]: 目标文件夹进行subAgent，找错文件夹

## QwenPaw Version
2.1.0，win
以A路径文件夹为项目文件夹，进行subAgent任务时，去B路径文件夹（这个是不以文件夹为项目的普通Agent默认的路径）找资料，不应该从A路径找吗？中途也没提醒我找到相应资料去干活没？
也不知道是否没有相应资料就直接跳过基于某些资料的任务还是直接用缓存资料。

The issue names no files, tests, or entry points. Reproduce the subAgent task on Windows with project folder A and the ordinary Agent default folder B, then trace how each agent resolves its working directory and gathers materials. Done means the subAgent searches A, reports when required materials are missing, and its behavior around skipped or cached material is explicit.
