reframe_animation

The first reframe on a controller mount is instant ( synchronous cy. fit + cy. center ) so the graph appears immediately on first paint.
Every subsequent reframe — automatic ( auto_reframe ) or manual ( manual_reframe ) — animates pan and zoom smoothly over GRAPH_REFRAME_ANIMATION_MS using cytoscape. animate ( { fit, easing: ' ease-out-cubic ' } ).
Callers may pass `reframeToViewport({ animate: false })` to force an instant reframe.
Initial batch layouts use fit: false ( see graph_cytoscape ) so the controller owns the first fit and later animated handoffs are not double-applied.
