Anthropic Messages API 的流式转发路径（gateway_service.go）在上游长时间 无数据时（如 Opus extended thinking 阶段）不会向下游发送任何内容，导致 Cloudflare Tunnel 等代理因连接空闲而断开。 复用已有的 StreamKeepaliveInterval 配置（默认 10 秒），在 select 循环中 添加 keepalive 分支，定时发送 Anthropic 原生格式的 ping 事件保活，与 OpenAI 兼容路径的实现模式保持一致。 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
