Introducing the DeepSeek Harness Plugin: satan9394/dsh-e2e-testing

`-9394/dsh-e2e-testing` is a plugin for DeepSeek Harness (DSH) designed to address the high cost of existing test integrations. It supports the Playwright and Cypress frameworks, enabling developers to run Web end-to-end tests directly within the DSH ecosystem without additional tools. The plugin runs with the permissions of the current process, so caution is required regarding privilege isolation and security risks. Since official installation commands and detailed usage instructions are not provided, users must refer to the source code or project page to set it up manually.
