server-workbench-http.ts: - handleWorkbenchRealtimeHttp 优先从 durable outbox 读取 (readWorkbenchProjectionOutbox) - 当 runtimeStore 支持 outbox 时，SSE 用 polling cursor replay 代替 traceStore.subscribe - outbox 不支持时保留内存 traceStore.subscribe 作为兼容降级 - terminal commit 从 outbox terminal 行触发 snapshot + trace realtime - 新增 HWLAB_WORKBENCH_SSE_OUTBOX_POLL_MS 环境变量控制 poll 间隔 workbench-facts-store.ts: - 新增 subscribeDurableProjection 方法，从 durable outbox polling 读取 - subscribeTrace 保留兼容（内存 trace），新增 durable projection subscription 入口 - SPEC header 更新到 draft-2026-06-20-p1-zero-split-durable-realtime cloud-api 重启后 SSE 从 DB outbox cursor 继续输出，不依赖内存 listener Closes #1748 Refs #1742
