Fix: Resize-Handles als absolute Overlays statt Grid-Spalten
Komplett neuer Ansatz: Handles sind absolut positionierte 8px-Elemente über den Panel-Grenzen statt schmale Grid-Spalten. Behebt das Problem dass WebKitGTK Mouse-Events auf engen Grid-Zellen nicht registriert. - Handles position:absolute über kumulierten Panel-Breiten - 8px breit, transparent, wird blau beim Hover - Drag-Overlay (position:fixed) fängt Events während Drag - document.addEventListener statt window für bessere Kompatibilität Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
