temporary-workspace 2

DSH 临时任务模式：为 DSH 增加「任务」分组——不绑定任何长期工作空间，自动在任务根目录下创建隔离的临时工作目录并开启会话，即开即用、用完即弃。Temporary task mode for DeepSeek Harness.

DSH web client plugin: a temporary workspace (临时工作区) — every conversation it contains is deleted at the next Harness restart (immediately or after a delay), optionally behind a confirm dialog. Adds a small icon beside the sidebar's "Add workspace" button
