 说明：
 
 - `start` 会先启动后端，再启动前端；普通 `start` / `restart` 不检查、不下载、不安装更新，DEV 模式也不例外
+- 本地 CLI 会优先使用项目根目录 `venv/bin/moviepilot-python`；该入口不存在时回退到同一目录的 `venv/bin/python`，手工启动、更新和开机自启保持一致
 - `start --safe` 会以安全模式启动后端，本次启动跳过插件、调度器、监控、命令和工作流等后台扩展能力，不修改用户配置
 - `MOVIEPILOT_AUTO_UPDATE` 为布尔开关，默认 `false`；只有 `true` 启用后台 Release 检查和版本提醒，保存后定时服务热更新。`AUTO_UPDATE_RESOURCE` 独立控制站点资源检查和提醒；任一开关开启即启用检测服务，且只检查对应目标，两者均关闭才移除服务。`MOVIEPILOT_UPDATE_DEV` 为独立布尔开关，默认 `false`；设为 `true` 时手动 `moviepilot update` 默认使用 DEV 更新模式。旧 `dev/release` 值统一转换为 `MOVIEPILOT_AUTO_UPDATE=true`；旧 `dev` 在未显式配置新开关时迁移为 `MOVIEPILOT_UPDATE_DEV=true`
 - Release 更新由后台每 6 小时检查 GitHub Release；管理员确认后先静默下载安装包并显示进度，下载完成后再次确认重启，通过专门的内部更新入口安装已下载且通过 SHA-256 校验的包后再启动服务
