dsh-nitrite-safe: Nitrite Safety Plugin

`dsh-nitrite-safe` is a Node.js plugin for DeepSeek Harness (DSH), maintained by uckkk. It focuses on curing safety and provides nitrite-related solutions through purely local computations without relying on the network. It depends on specific versions of `@deepseek-ai/cordis` and `@deepseek-ai/dsh-tools`. Users can install it with the official command and, once installed, use it by directly invoking the registered tools in a session. The plugin runs with the current process’s permissions; we recommend reviewing its source code and MIT license before installation.
