fix(graph): skip inward convergence during drag to preserve bounded follower pull

applyGalaxyInwardConvergence runs after applyDraggedNodeGravity and
projects all community centers radially toward the black hole. This
overwhelms the bounded ≤2-unit drag displacement on follower nodes,
causing unlinked bodies to move away from the drag direction. During
a drag gesture (120ms), convergence is imperceptible and should not
compete with the user's intentional pointer movement.
