"""WorkBuddy Portal —— 统一命令行入口。

采集 / 存储 / 呈现三件事都由本项目承担，不再依赖外部计划任务或自动化。

多用户说明：所有涉及「数据」或「凭证」的子命令都作用于**某一个账号**。
用 `-u/--user <用户名>` 指定；不指定时取「管理员优先、其次 id 最小」的那个
（老库升级后数据都在首个账号名下，所以不指定也能沿用旧习惯）。
唯独 `collect` 不带 `-u` 时会**逐个账号**跑一遍，与进程内调度线程的行为一致。

常用：
  python manage.py init                       初始化数据库（建表 + 默认配置 + 管理员）
  python manage.py serve                      启动 Web（0.0.0.0:8848，进程内含调度线程）
  python manage.py serve --port 9000 --debug  开发模式（reloader 下调度只启动一份）
  python manage.py collect                    为**所有已启用账号**各跑一次增量采集
  python manage.py collect -u alice           只为 alice 采集
  python manage.py migrate-csv [文件]          从旧版 CSV 存档导入（默认自动探测路径）
  python manage.py import-xlsx <文件>          从官网导出的 xlsx 合入
  python manage.py fill-prompt                补全缺失的 User Prompt
  python manage.py export-csv [路径]           导出与官网同构的 CSV（文件名带账号名）
  python manage.py stats [-u 账号]             看存档概况，不联网
  python manage.py users                      列出所有账号及其数据量 / 凭证状态
  python manage.py passwd <用户名> [新密码]     重置密码；账号不存在则创建
  python manage.py passwd <用户名> --role admin  新建或提权为管理员
  python manage.py status                     查看各账号的调度与最近采集状态
  python manage.py vacuum                     整理数据库（checkpoint + VACUUM）
  python manage.py backup                     立即打一份备份（所有 *.sqlite + instance.json）
  python manage.py backups                    列出备份；--prune 按保留份数清理最旧的
  python manage.py restore <文件名> --yes      从备份恢复（恢复前会自动再备份一份当前库）
