dsh-im-bridge: DeepSeek Harness IM Channel

dsh-im-bridge is an IM channel plugin for DeepSeek Harness (DSH), maintained by shaobeichen and licensed under the MIT License. The tool aims to enable users to operate outside the web interface, allowing them to remotely dispatch tasks to DSH, receive result notifications, and approve dangerous operations via instant messaging tools such as Lark, WeCom (WeChat Work), or Telegram. Core features include: sending task commands directly within the IM; an approval mechanism for dangerous operations that defaults to rejection and requires confirmation to execute; proactive notifications for task completion or failure that include execution time and token usage; automatic truncation of long outputs with full text export available via the `/log` command; session management commands such as `/new` and `/status`; and role-based (admin/regular user) permission control, restricting management access to administrators.
