feat: 添加可选的代理功能支持

新增功能:
- 集成 Cloudflare WARP socks5 代理服务
- 通过环境变量 USE_PROXY 控制代理开关
- 支持自定义 HTTP/HTTPS/SOCKS5 代理服务器
- 使用 docker compose profile 管理 proxy 服务

配置方式:
- USE_PROXY=true 启用代理
- ALL_PROXY/HTTP_PROXY/HTTPS_PROXY 自定义代理
- docker compose --profile proxy up 启动 warp 服务

文件变更:
- docker-compose.yaml: 添加 warp-proxy 服务
- playwright-auth.ts: 添加代理配置逻辑
- example.env: 添加代理环境变量
- PROXY.md: 使用文档

docker-compose.yaml
