dsh-anti-theft: Anti-Theft Configuration Tool for DeepSeek Harness

The DeepSeek Harness plugin `dsh-anti-theft` is a pure Node.js plugin focused on anti-theft scenarios and runs without network requests. Maintained by developer uckkk, it provides the `anti_theft` tool, which returns clear anti-theft recommendations based on the input parameters. The plugin depends on `@deepseek-ai/cordis` and `@deepseek-ai/dsh-tools`, is licensed under the MIT License, and can be invoked directly after installation. Because it runs with process privileges, it is recommended to review the source code before installation to ensure security.
