P3-A: Token Runtime 缓存层实现 - HTTPTimeout/LRU淘汰/命中率指标
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
