zeta987/dsh-notify-zeta: DeepSeek Harness Notification Center and Interactive Windows Cards

`zeta987/dsh-notify-zeta` is a community-built plugin for DSH, designed to address the lack of instant status feedback in task scheduling and approval workflows. It provides a built-in notification center that supports single-select, multi-select, text input, and approval actions through native Windows WPF popups, and also offers browser notifications as a secondary channel. Users can finely control 14 event toggles, and the language automatically follows the system. Installation requires Node.js 22.19.0+; native features are limited to Windows 10/11 and depend on the DSH process remaining active.
