// 未填 Token 时，GitHub API 每小时只有约 60 次请求额度，浏览仓库一多就会触发 403 限流，
// 标签就会突然不显示。强烈建议生成 Token 填到下面：
// 1. 打开 https://github.com/settings/tokens
// 2. 「Generate new token」→「Generate new token (classic)」
// 3. 读取公开仓库大小不需要勾选任何权限（scope），直接生成即可
// 4. 把生成的 ghp_... 粘贴到下面两个引号之间
// 填了 Token 后额度提升到每小时 5000 次，基本不会再触发限流。
