DeepSeek Harness Plugin: Push Task Completion Messages to Huawei's Negative One Screen

`dsh-hiboard-push` is a plugin for DeepSeek Harness (DSH) that synchronizes task completion messages to Huawei Hiboard (Negative One Screen) in real time. The plugin uses `authCode` for authentication and provides two tools: `hiboard_push` and `hiboard_verify`. `hiboard_push` can send cards containing a task's name, content, and status, supporting standard tasks, recurring tasks, and summary-only mode. Developers can install and configure the plugin via the terminal to enable visual synchronization of information between agents and mobile devices.
