.SYNOPSIS
启动阿里云开发环境服务 - 符合大厂标准的启动脚本

.DESCRIPTION
功能：
1. 加载环境配置文件
2. 从环境变量读取敏感配置（符合安全规范）
3. 分阶段启动基础设施和业务服务
4. 支持健康检查验证

.PARAMETER EnvFile
环境配置文件路径

.PARAMETER SkipLogin
是否跳过镜像仓库登录

.EXAMPLE
# 使用默认配置启动
.\scripts\start-aliyun-env.ps1

# 指定配置文件
.\scripts\start-aliyun-env.ps1 -EnvFile .\infrastructure\compose\.env.aliyun

# 跳过登录（已登录状态）
.\scripts\start-aliyun-env.ps1 -SkipLogin
#>
