# 安装 / 卸载 / 查看技能治理的定时任务（macOS 用户级 launchd）
#
# 为什么用 launchd 而不是会话提醒：会话提醒随会话消失，节拍就断了；
# launchd 是宿主级，跟仓库绑定，换机器重跑一次即可复现。
#
# 用法:
#   ./scripts/install-schedulers.sh                  安装（幂等，会先卸载再装）
#   ./scripts/install-schedulers.sh --status         看三个任务的加载状态
#   ./scripts/install-schedulers.sh --run daily      立刻跑一次（调试用）
#   ./scripts/install-schedulers.sh --uninstall      卸载
