dsh-plutonium: A Pure Node Plugin with No Network Dependencies

dsh-plutonium is a plugin designed specifically for DeepSeek Harness (DSH) to enable feature extension in offline environments. It is implemented entirely in Node.js, without relying on any network requests, and integrates via the `cordis.patch.yml` patching mechanism. It requires `@deepseek-ai/cordis` version 4.0.1 or higher and `@deepseek-ai/dsh-tools` version 0.1.0-rc.6 or higher. Once installed, the plugin is granted the permissions of the current DSH process, making it suitable for deployment in network-restricted or isolated scenarios to perform model inference tasks.
