OpenWebUI 社区统计工具

获取并统计你在 openwebui.com 上发布的插件/帖子数据。

使用方法：
    1. 设置环境变量：
       - OPENWEBUI_API_KEY: 你的 API Key
       - OPENWEBUI_USER_ID: 你的用户 ID
    2. 运行: python scripts/openwebui_stats.py

获取 API Key：
    访问 https://openwebui.com/settings/api 创建 API Key (sk-开头)

获取 User ID：
    从个人主页的 API 请求中获取，格式如: b15d1348-4347-42b4-b815-e053342d6cb0
