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

Browse Source 
- 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)

//! `gioser-graph-web` — widget de grafo semántico SVG inline.
//!
//! Fetchea `GET /graph` de la API de gioser, parsea nodos + aristas,
//! y renderiza un grafo SVG interactivo dentro de un contenedor dado.
//!
//! Los nodos son **rectángulos redondeados** horizontales con el texto
//! dentro (no círculos) para mejor legibilidad. Las aristas varían en
//! grosor según la intensidad semántica (k-NN weight).
//!
//! ## Contrato DOM
//!
//! El caller pasa un `<div>` contenedor y un callback `on_navigate(doc_id)`.
//! El widget monta un `<svg>` dentro con viewBox fijo.
//! Layout grid: 3 columnas, filas según la cantidad de nodos.
//! Los nodos son rectángulos redondeados con texto + subtexto (camino).
//! Aristas se dibujan entre todos los pares con líneas semitransparentes:
//! mientras mayor el weight, más opaca y brillante la línea.
//! Animación CSS de respiración suave en el SVG.
//! Hover: glow + opacidad.
