Set up the initial file system for a new sandbox. Fetches the account's organizations and artists via the Recoup CLI and scaffolds an opinionated folder structure. Use when a sandbox has just been created and has no existing file system. Before running, check if the sandbox already has an orgs/ directory — if it does, this skill is not needed.

为新沙盒设置初始文件系统。通过 Recoup CLI 获取账户的组织和艺术家信息，并构建一套有明确结构的文件夹体系。仅在沙盒刚创建且尚未存在文件系统时使用。运行前请检查沙盒是否已存在 orgs/ 目录，若已存在则无需执行此操作。
