- 新增统一代理工具 ProxyHelper，支持 SOCKS5/HTTP/HTTPS 代理 - 添加 IPv4/IPv6 协议族配置选项，默认使用 IPv4 确保兼容性 - 移除 OpenAI 路由中硬编码的 family: 4 限制 - 统一 8 个服务文件中的代理创建逻辑，避免重复维护 - 支持 OAuth 和 token 交换过程中的代理使用 - 新增配置项：PROXY_USE_IPV4（默认 true） - 向后兼容：现有配置无需手动更新 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
