dsh-astatine: A Pure Node.js Plugin with No Network Dependencies

dsh-astatine is a pure Node.js plugin for DeepSeek Harness (DSH), designed to address the lack of tools for localized data processing and network-restricted environments. It requires no internet connection and relies entirely on the Node.js runtime, making it suitable for offline or intranet scenarios. Installation requires the DSH environment dependencies and runs with the permissions of the current process. It fills the gap of network-independent tools in the DSH ecosystem and is well suited for building localized agents with low network requirements.
