dsh-cloud-connector: SSH Connection Manager for DSH Cloud Servers

The DeepSeek Harness (DSH) plugin `dsh-cloud-connector` provides visual SSH cloud server connection management. It supports adding servers, configuring port tunnels, and setting auto-connection on startup through the web interface, with persistent configuration storage. The plugin provides a series of `cloud_*` conversational tools that allow direct command execution, file transfer, GPU monitoring, and environment management from the chat window. Installation requires using the `dsh plugin` command or manually configuring dependencies. When using it, pay attention to private key path configuration and Chinese path compatibility issues on Windows.
