+- 本机 `dsh web` 与 DSH Desktop 的 IM 渠道和 AI Office 现在默认直接使用当前 Host 的内部 `apiProxy`，不再依赖回环 HTTP 端口或 Desktop 的浏览器/局域网访问开关；显式配置 `harnessBaseUrl` 时仍使用 HTTP/WebSocket，内部调用失败不会静默切换 Host。
+  IM channels and AI Office in local `dsh web` and DSH Desktop now use the current Host's internal `apiProxy` by default, removing the dependency on loopback HTTP ports or Desktop's browser/LAN access settings. Explicit `harnessBaseUrl` configurations still use HTTP/WebSocket, and failed internal calls never silently switch Hosts.
