/**
 * scripts/agent-checkin.js
 * 人格体每日签到脚本
 *
 * 逻辑：
 * 1. 读取 agent-registry.json 获取所有注册小兵列表
 * 2. 对每个小兵，查询 GitHub Actions API 获取该 workflow 今日最新一次 run 的结果
 * 3. 结果为 success 且时间在今天 10:00 之前 → 标记为 ✅ 已签到
 * 4. 结果为 failure 或无今日 run → 标记为 ❌ 未签到
 * 5. 更新 checkin-board.json 的所有记录
 * 6. 生成 summary（总数/已签到/缺席/缺席名单）
