The two black terminals had two causes: uvicorn --reload (a dev flag whose
reloader spawns the server as a child, and Windows gives a console window to a
child of a console-less parent), and DETACHED_PROCESS in launch(), which is
exactly the console-less condition that triggers it. Drops --reload here
(launch_nexus.sh keeps it for the Linux dev loop) and uses CREATE_NO_WINDOW.
The window now opens immediately on an inline 'Loading Nexus core services' page
and navigates to the app once /status answers, instead of waiting 40s offscreen.
