gioser-graph: grid layout 3 cols, line brightness by weight, breathing animation

- Replaced force-directed layout with explicit grid: 3 columns wide,
  rows based on node count (minimum 3 visual rows)
- Nodes are larger: 170x44px with 8px radius
- Lines: color brightness + stroke opacity based on normalized weight
  (weight 1.0 → white #ffff, 0.5 → dimmer rgb)
- CSS animation 'graph-breathe': opacity pulses slowly (4.2s ease-in-out)
- Hover: drop-shadow glow + fill-opacity increase
- Glow circle behind each node (subtle)
