dsh-pakistan: Pakistan National Networking Tool Plugin

`dsh-pakistan` is a lightweight networking plugin for DeepSeek Harness (DSH), specifically designed to handle Pakistan-specific network operations. It is written in pure Node.js, has no network dependencies, and runs stably. Developers must meet the version requirements for `@deepseek-ai/cordis` and `@deepseek-ai/dsh-tools` and can install it using the `dsh plugin add` command. The plugin starts together with the DSH process and is suitable for scenarios requiring the configuration of region-specific networking capabilities. It is recommended to consult the source code to confirm the specific API invocation methods.
