dsh-bento: Bento Pairing Tool

The DeepSeek Harness plugin `dsh-bento` is a bento pairing calculator focused on fun scenarios, maintained by developer uckkk. By registering the `bento` tool, it supports precise calculations based on parameters and returns clear pairing suggestions. As a pure Node implementation, it does not rely on network requests. Installation requires the dependencies `@deepseek-ai/cordis` (^4.0.1) and `@deepseek-ai/dsh-tools` (>=0.1.0-rc.6), and can be completed with the command `dsh plugin add github:uckkk/dsh-bento`. The plugin is licensed under the MIT License and runs with the permissions of the current process.
