Introduction to the DeepSeek Harness (DSH) Business Bridge Plugin

`newspringwei/dsh-biz-bridge` is a business bridge plugin for DeepSeek Harness, designed to simplify business system integration via the standard HTTP protocol. It provides streaming/callback responses, multi-turn conversations, bidirectional attachment forwarding, and security validation, and supports SQLite storage. Users must install Node.js and the DSH environment, enable the plugin using the `dsh plugin` command, and use key authentication. As the version is in its early stage, it is not recommended for critical production paths.
