Manage spaces, folders and files in WeChat Work WeDrive (企业微信微盘) via wiseflow-relay — create space, create folder, upload image/video, list, info, rename, move, delete, and share files via file-level share link. Standard flow 建空间 → 传文件 → file-share 发分享链接给同事. Credentials (corp_id + corp_secret) read from daemon.env and passed per-request; relay is stateless. Space/folder IDs cached locally in spaces.json.
