What

Phase 1 of #210: WebSocket 反向连接替代 Cloudflare Tunnel。

Why

Cloudflared tunnel 依赖外部工具、KV heartbeat TTL 脆弱、URL 漂移导致 530。WS 反向连接零外部依赖，连接即注册，断开即离线。

Changes

Gateway (packages/workflow-gateway/)

  • src/agent-socket.ts — 新增 AgentSocket Durable Object，per-agent 持有一个 WS 连接，支持 status 查询和新连接替换旧连接
  • src/index.ts — 新增 /ws/connect 路由（GATEWAY_SECRET 认证 + WS upgrade 转发到 DO）；endpoints 列表合并 KV + DO 状态
  • wrangler.toml — 新增 AGENT_SOCKET DO binding + migration

Agent (packages/cli-workflow/src/commands/serve/)

  • ws-client.ts — 新增 WS 客户端，指数退避自动重连（1s→30s），Phase 2 请求处理占位
  • serve.ts — 默认走 WS 模式（不再自动启 cloudflared），保留 --tunnel-url 和 --no-tunnel fallback
  • types.ts — 新增 tunnelUrl 字段

Testing

#211 验证步骤：

  • ✅ Step 1: Gateway healthz 正常
  • ✅ Step 2: serve 启动后 WS 连接建立
  • ✅ Step 3: endpoints 返回 status: "online"
  • ✅ Step 4: 停止 serve 后从 endpoints 列表消失
  • ✅ Step 5: 代码含指数退避重连逻辑

feat: WebSocket reverse-connection gateway Phase 1 (#210) 321b5431f4 
- Add AgentSocket Durable Object (holds one WS per agent name)
- Add /ws/connect route with GATEWAY_SECRET auth
- Add ws-client.ts with auto-reconnect (exponential backoff 1s-30s)
- serve defaults to WS mode (no cloudflared needed)
- Keep --tunnel-url and --no-tunnel as fallback options
- Endpoints list merges KV heartbeat + DO WebSocket status

Testing: #211

LGTM. Clean phase 1: proper null checks replacing non-null assertions, functional ws-client with exponential backoff, DurableObject class acceptable as CF platform requirement. Conventions followed.
