.SYNOPSIS
统一部署脚本 - 符合大厂标准的自动化部署工具

.DESCRIPTION
功能：
1. 支持多环境部署（dev/test/prod）
2. 参数化构建选项
3. 完整的日志记录
4. 健康检查验证
5. 通知告警机制

.PARAMETER Environment
部署环境：dev/test/prod（默认：dev）

.PARAMETER Services
指定要部署的服务列表，默认全部

.PARAMETER BuildBackend
是否构建后端服务（默认：true）

.PARAMETER BuildFrontend
是否构建前端项目（默认：true）

.PARAMETER BuildImages
是否构建容器镜像（默认：true）

.PARAMETER PushImages
是否推送镜像到仓库（默认：false）

.PARAMETER SkipTests
是否跳过测试（默认：true）

.PARAMETER Verify
是否执行健康检查（默认：true）

.EXAMPLE
# 部署到开发环境
.\scripts\deploy.ps1 -Environment dev

# 部署到生产环境并推送镜像
.\scripts\deploy.ps1 -Environment prod -PushImages -SkipTests:$false

# 只部署特定服务
.\scripts\deploy.ps1 -Services auth-service,user-service

# 完整构建并部署
.\scripts\deploy.ps1 -BuildBackend -BuildFrontend -BuildImages -PushImages -Deploy -Verify
