dsh-wsl-dns: A WSL and Windows DNS Resolution Comparison Tool

`dsh-wsl-dns` is a plugin designed to resolve DNS lookup issues for DeepSeek Harness (DSH) in WSL environments. It compares DNS resolution results between WSL and Windows, flags endpoints with inconsistent lookups (such as GitHub and npm), and helps developers quickly troubleshoot network connectivity issues. The plugin runs with the current process permissions, does not modify proxy settings, and requires DSH >= 0.1.2 and Node.js >= 18.
