fix: 检查栈帧大小 (#1126)

Browse Source 
* feat: 打开clippy的stack overflow静态检查

*限制栈大小最大为4096字节
*限制栈中的数组最大为1024字节

* fix: 修复部分函数的爆栈问题 (#1172)

* fix:修复部分函数的爆栈问题

* feat(filesystem): 重构FAT文件系统重命名和移动文件逻辑

将rename_file_in_same_dir和move_file_to_other_dir函数重构为LockedFATInode的方法，优化代码结构。同时更新clippy配置，添加栈大小和数组大小阈值。
