market_sync/deploy/systemd/scripts/systemd_deploy.sh

#!/bin/bash
# market_sync systemd 一键部署脚本
#
# 用途：把 bin/systemd/*.service 和 *.timer 同步到 /etc/systemd/system/，
#       解决 work #04 检测到的 5 处 drift。
#
# 运行：sudo bash bin/systemd_deploy.sh
#
# 设计原则：
#   - 必须 sudo（写 /etc/systemd/system/ + daemon-reload）
#   - 幂等：重复运行无副作用
#   - 显示 plan → 等待确认 → 执行
#   - 失败立即中止，不留半套状态
