dsh-mini-store: Minimalist Storage Rules

`dsh-mini-store` is a DeepSeek Harness (DSH) plugin maintained by uckkk, designed to provide a minimal state management solution. Fully implemented with Node.js and free of web dependencies, its core feature is a minimalistic keep/discard mechanism driven by parameters, which simplifies storage logic. Developers can install it with the `dsh plugin add` command and enable it simply by invoking its tools in a session. Since the plugin runs with the current process’s permissions, its source code and MIT license should be reviewed before use.
