feat: 提前记录 pending 用量、优化流遥测时序与前端活跃请求发现机制

- 将 record_pending 调用移至执行开始前（sync/stream 两路），确保请求在执行前即有 pending 记录 - stream_pump 在收到第一个数据块前优先 yield 遥测帧，保证 ttfb 早于 data 帧到达 - stream execution 增加 should_refresh_stream_usage_telemetry，在遥测帧携带新 ttfb/elapsed 时及时更新 record_stream_started - access_log 对高频轮询路径（usage/active、usage/records 等）降级为 TRACE 日志，减少日志噪音 - 前端新增 reconcileActiveRequestDiscovery 工具函数及 discoverActiveRequests 逻辑，活跃请求发现与全局自动刷新解耦，空闲时降频为 5 秒扫描 - RequestDetailDrawer 调整：进行中请求不再自动开启轮询，由用户手动触发；刷新按钮 title 动态适配状态
