dsh-guid: DeepSeek Harness GUID Generation Plugin

`dsh-guid` is a DeepSeek Harness (DSH) plugin maintained by developer uckkk, focused on generating globally unique identifiers (GUIDs) locally. The plugin is implemented in pure Node.js, does not depend on external network interfaces, and runs directly within the DSH process context. Users can install it using the `dsh plugin add` command and invoke its registered tools in a session. Since the plugin runs with the current process's permissions, please ensure the source code is secure. For specific interfaces, refer to `cordis.patch.yml` or the README in the source code.
