Feat: Gedächtnis-Tab überarbeitet — Sigma.js-Graph (skaliert), Liste als Default + gruppiert

Graph: reagraph (three.js, schwer, hing Renderer) → Sigma.js v3 + graphology (graph-optimiertes WebGL,
skaliert auf tausende Knoten), im App-Look: Kategorie-Farben, Knotengröße nach Verknüpfungen,
Hover-Highlight (Nachbarn hervor, Rest dimmt), Legende. Liste ist jetzt Default + nach Kategorie
gruppierte Sektionen (statt flacher Wand). reagraph deinstalliert → leichteres Bundle.
