// 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
