feat: 品牌重命名 Sub2API -> TianShuAPI
- 前端: 所有界面显示、i18n 文本、组件中的品牌名称
- 后端: 服务层、设置默认值、邮件模板、安装向导
- 数据库: 迁移脚本注释
- 保持功能完全一致,仅更改品牌名称

// reqClientOptions 定义 req 客户端的构建参数
type reqClientOptions struct {
ProxyURL string // 代理 URL支持 http/https/socks5
Timeout time.Duration // 请求超时时间
Impersonate bool // 是否模拟 Chrome 浏览器指纹
}
// sharedReqClients 存储按配置参数缓存的 req 客户端实例
//
// 性能优化说明:
// 原实现在每次 OAuth 刷新时都创建新的 req.Client
// 1. claude_oauth_service.go: 每次刷新创建新客户端
// 2. openai_oauth_service.go: 每次刷新创建新客户端
// 3. gemini_oauth_client.go: 每次刷新创建新客户端
//
// 新实现使用 sync.Map 缓存客户端:
// 1. 相同配置(代理+超时+模拟设置)复用同一客户端
// 2. 复用底层连接池,减少 TLS 握手开销
// 3. LoadOrStore 保证并发安全,避免重复创建
var sharedReqClients sync.Map
// getSharedReqClient 获取共享的 req 客户端实例
// 性能优化:相同配置复用同一客户端,避免重复创建
