gioser-graph: exaggerated thickness & brightness, edges behind with pointer-events:none

- Stroke width: 1.5 + w*8.0 (range 3-10px) for dramatic variation
- Brightness: w*0.7 factor, low weight = pure blended color, high weight ≈ white
- Opacity: 0.40 + w*0.55 (40-95%)
- Edges group gets .gb-edge-group { pointer-events: none } so clicks pass to nodes
- Visual layer: edges_group (behind) → nodes_group (front) in SVG
