dsh-eac-popup: Persistent EAC Taskbar Highlighting and Automatic Session Switching

dsh-eac-popup is a DeepSeek Harness EAC workflow plugin designed to address the issue of users easily missing notifications when an Agent runs background tasks or requests approval. By invoking Windows system interfaces, it provides features such as a persistently highlighted taskbar icon, automatic session switching, and an always-on-top window. It is mounted at the host level, covers all sessions, and remains effective after restarts. Installation requires pairing it with the web-desktop profile and the EAC main process patch, and it is intended for Windows environments.
