+- 本机 `dsh web` 与 DSH Desktop 现在同时兼容旧版和当前版 Host：旧版继续复用内部 `apiProxy`，当前版自动适配 Typert Gateway、Session Controller 与 Workspace Controller；两者都无需回环 HTTP 地址，并继续隔离不同 Host 的会话、审批与问题交互。显式 `harnessBaseUrl` 仅保留给旧版远程 HTTP/WebSocket Harness。
+  Local `dsh web` and DSH Desktop now support both legacy and current Hosts. Legacy releases continue to reuse the internal `apiProxy`, while current releases automatically adapt the Typert Gateway plus Session and Workspace controllers. Neither requires a loopback HTTP address, and Sessions, approvals, and questions remain isolated between Hosts. Explicit `harnessBaseUrl` is retained only for legacy remote HTTP/WebSocket Harness endpoints.
