xmanrui/dsh-dingtalk: Integrating DingTalk into DeepSeek Harness by Scanning a QR Code

`xmanrui/dsh-dingtalk` is a DingTalk bot integration plugin for DeepSeek Harness. This plugin processes messages through a persistent DingTalk Stream connection within the Host process, supports scanning a QR code to authorize bot creation, and securely stores sensitive credentials in the Harness service. It supports private text messages and group chat conversations where the bot is explicitly mentioned, provides commands such as `/new`, `/status`, and `/help`, and can render AI Cards. Installation requires DeepSeek Harness `0.1.0-rc.6` and Node.js `>=22.19`. **Note: This project is no longer maintained, and it is recommended to use the unified `dsh-im` plugin instead.**
