Phase 3-A 完整实现，包含: Gateway (lijiaoqiao/gateway): - RemoteTokenRuntime 缓存实现: active=30s/expired=2m/revoked=10m TTL淘汰 - LRU 容量淘汰 (max_entries=10000，插入顺序淘汰) - HTTPTimeoutConfig: 4个环境变量 (Dial/KeepAlive/Read/Write/MaxIdle) - 缓存命中率指标: GetCacheHitRate() + 实例级别统计 - 上游延迟指标: RecordTokenRuntime() histogram - buildTimeoutClient: 基于 HTTPTimeoutConfig 的 HTTP 客户端工厂 - 新增测试: 22个矩阵测试 (remote_runtime_matrix_test.go, config_test.go) Platform Token Runtime (lijiaoqiao/platform-token-runtime): - metrics/metrics.go: GetCacheHitRate() 方法 - inmemory_runtime.go: GetCacheHitRate() 实现 变更文件 (8 modified + 5 new): - gateway/internal/middleware/remote_runtime.go # 核心缓存实现 - gateway/internal/middleware/remote_runtime_test.go - gateway/internal/middleware/remote_runtime_cache_test.go - gateway/internal/middleware/remote_runtime_matrix_test.go - gateway/internal/middleware/remote_runtime_metrics_test.go - gateway/internal/metrics/metrics.go # 新增 - gateway/internal/config/config.go # HTTPTimeoutConfig - gateway/internal/config/config_test.go - gateway/internal/app/bootstrap.go # 初始化顺序 - gateway/internal/router/router.go # 指标注入 - platform-token-runtime/internal/metrics/metrics.go # 新增 - platform-token-runtime/internal/app/bootstrap.go - platform-token-runtime/internal/auth/service/inmemory_runtime.go
