HomeAgent/deploy/scripts/deploy-plan.sh

#!/bin/bash
# 生产部署方案（**待确认，不自动执行**）
#
# 用法：
#   bash deploy/scripts/deploy-plan.sh check     # 只做部署前检查，不改任何东西
#   bash deploy/scripts/deploy-plan.sh backup    # 备份当前二进制与适配器
#   bash deploy/scripts/deploy-plan.sh deploy    # 替换二进制并重启（需显式确认）
#   bash deploy/scripts/deploy-plan.sh rollback  # 回滚到备份
#
# ★ 本脚本刻意**不包含**任何"自动回滚"逻辑：回滚要不要做、什么时候做，
#   是人的判断。脚本只负责把状态保全好，让回滚成为一条可执行的命令。
