gioser-web: hash routing, clickable graph nodes, hover bounce, line normalization

- Hash routing: each page sets location.hash to #/element (aire/fuego/etc)
  - Hash read on boot to open direct URL
  - hashchange listener for browser back/forward
  - minimize clears hash
- Graph node click: dispatches click on the corresponding .tip element,
  triggering page open animation (expand from center)
- Graph hover: CSS bounce animation (scale 1→1.08→0.96→1, 0.4s)
- Edge normalization: min-max scale (w-0.80)/0.15 then squared curve
  for visible weight differentiation in tight cluster (0.83-0.93)
