fix(ai): 生成收尾不再只依赖 __END__，并清掉 WS 死代码

- handleGenerate 收尾改 try/catch/finally：loading 一定复位。原先只在收到
  __END__ 帧时由 finishStream 复位，网关返回空流或上游中途报错时按钮会永久
  停在加载态（issue 20）
- 提示按结果区分：没有正文 → 提示重试；正文是失败文案 → 报错；否则才是成功
- 删掉已不会调用的 WebSocket 栈：connectWebSocket / disconnectWebSocket /
  wsConnected / webSocketRef / wsConnectPromiseRef / activeConversationId，
  以及随之失效的 attachHeartbeat、buildWebSocketUrl、useUserStore 与
  StreamResolver.reject
- 大纲页删掉早已无调用点的 parseOutline（SSE 改造后遗留）及其 import
