HKUDS/OpenSpace

This issue indicates a fundamental problem with the `openspace-dashboard` command's availability or installation. A "command not found" error for a core component like a dashboard suggests either incomplete installation instructions, a broken installation script, or an environmental path issue. This directly impedes user interaction with the OpenSpace system, preventing access to agent management and monitoring functionalities. Such basic operational failures create significant friction for new users, undermining the "smarter, low-cost, self-evolving" promise by making the system inaccessible or difficult to manage.
