dsh-bean-choice: Bean Selection Recommendations

`dsh-bean-choice` is a plugin for DeepSeek Harness (DSH), developed by uckkk, designed to provide explicit parameter recommendations and decision support for agents or toolchains. The plugin is implemented entirely in Node.js, does not rely on network requests, and runs stably and efficiently. Before installation, dependencies such as `@deepseek-ai/cordis` and `@deepseek-ai/dsh-tools` must be satisfied. It runs with the permissions of the current process and is suitable for use in offline environments. It is recommended to review the source code before use.
