feat(litegraph): use layoutStore slot positions for node slot queries\n\n- Route getInputPos/getInputSlotPos/getOutputPos through getSlotPosition(), which prefers layoutStore DOM-tracked positions and falls back to geometry.\n- Ensures reroute-origin drags snap to visually tracked node slots when hovering compatible nodes in Vue nodes mode.\n- No change for non-Vue nodes mode or when no tracked slot layout is present.
