Fix: Resizable Panels via Pointer Events + setPointerCapture
Komplett auf Vanilla JS Pointer Events umgestellt: - setPointerCapture() fängt ALLE Events am Handle-Element (kein Overlay nötig) - touch-action: none auf Handles (WebKitGTK Kompatibilität) - addEventListener in onMount statt Svelte on: Syntax - Handles als sichtbare 8px Grid-Spalten (nicht absolute) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
