Introduction to the DeepSeek Harness SSH Tool Plugin (dsh-tool-ssh)

`dsh-tool-ssh` is an SSH tool plugin for DeepSeek Harness (dsh), designed to address remote host operation requirements. By invoking the local OpenSSH client, it achieves **zero agent deployment**, meaning the target machine only needs to support SSH login. The plugin provides three core functions: executing commands (`ssh_run`), uploading (`ssh_upload`), and downloading (`ssh_download`). During installation, ensure that both dsh and OpenSSH are installed locally. When using it, note that batch mode is enabled by default to avoid interactive prompts; key-based authentication is recommended, and the output stream has size limits to prevent memory overflow.
