DeepSeek Harness Plugin: dsh-quick-session (Quick Session Without Workspace)

`dsh-quick-session` is a DeepSeek Harness (DSH) client plugin maintained by GRmaid. It allows users to start sessions in the Web GUI without specifying a Workspace by automatically assigning an independent temporary directory under `%DSH_HOME%\scratch` as a sandbox boundary, simplifying the handling of temporary tasks. The plugin provides a sidebar shortcut entry; the host side creates directories and registers routes, while the browser side handles UI interactions. The Agent is granted workspace write and confirm-before-change permissions by default, and supports React 18 development debugging. Please note that temporary directories are not automatically cleaned up, and desktop installation requires using the `link:` method.
