延迟显示已修通。移除排查期的临时诊断:扩展侧 Log 客户端/klog 捕获、log.level=debug 注入、 diag 字段/setDiag;主 app StatsClient 每5帧的 dl/ul/urltest 打印;Dart 侧 [Stats]/[Ping] 打点。 保留全部修复:clash_api 注入取 urltest、sendProviderMessage 统计通道、/proxies history+active 缓存、共享广播流、_onStats 回退 effectiveNode、连接态跳过直连实测。 CURRENT_PROJECT_VERSION 52→53。 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
