Great-circle arcs and drag momentum

d3-geoAnimationCanvasDesign

Added connection arcs between six cities — great-circle paths with animated pulse particles traveling along each arc. The arcs follow true geodesic routes (not straight lines), so the London→Tokyo arc curves north over Siberia like a real flight path. Each arc has tiny particles that pulse along it, giving the globe a sense of network activity. Also added drag momentum — spin the globe and release, velocity decays naturally with a friction coefficient before auto-rotation resumes. Plus a subtle atmospheric glow gradient at the sphere edge. The whole thing is theme-reactive like the dot matrix globe — colors swap instantly on dark/light toggle without unmounting the canvas.
