dsh-wsl-clipboard: Reading and Writing to the Windows Clipboard in WSL

`dsh-wsl-clipboard` is a plugin for DeepSeek Harness (DSH), designed to address pain points in interacting between WSL and Windows. It allows agents to read from and write to the Windows clipboard (with UTF-8 text support) by calling PowerShell inside WSL, eliminating manual copy-and-paste. To install it, run the command `dsh plugin --profile web add github:173787247/dsh-wsl-clipboard` and restart the service. The tool supports the `get` and `set` actions, and allows adjusting the timeout and maximum character length limit in the configuration file. When using it, pay attention to version requirements and security, and avoid storing sensitive data in the clipboard.
