自动整理文件夹

@user_c4775d0f/jingmao-jk2-ljs-1zu-101

This skill should be used when the user asks to "organize files", "sort files", "clean up directory", "organize folder", "auto organize", "整理文件", "自动整理", or wants to tidy up a messy directory by classifying files into categorized subfolders. Also applies when the user wants to batch rename files, find duplicates, or clean empty folders.
