/**
 * Bookworm Smart Assistant - 自动磁盘清理脚本
 *
 * 功能:
 *   1. 清理 debug/ 目录 (保留最近 7 天)
 *   2. 清理 projects/ 会话日志 (非活跃项目 >14天, 活跃项目 >30天)
 *   3. 清理 projects/ tool-results 缓存 (>7天)
 *   4. 清理 shell-snapshots/ (保留最近 30 天)
 *   5. 清理 backups/ (保留最近 10 个)
 *   6. 磁盘健康度报告
 *
 * 使用方式:
 *   node auto-cleanup.js              # 预览模式 (dry-run)
 *   node auto-cleanup.js --execute    # 执行清理
 *   node auto-cleanup.js --report     # 仅输出 JSON 报告 (供 self-auditor 消费)
 *
 * 集成点:
 *   - self-auditor D8 维度: 读取 --report 输出
 *   - self-healer M5 模式: 调用 --execute 执行
 *   - 可配合 cron/Task Scheduler 定期运行
 *
 * 创建: 2026-02-20
