feat: 添加调试可视化工具和性能优化

- Task 10: 添加调试可视化工具 - DebugDrawFlowDirections() - 可视化材料流动方向 - DebugDrawEdgeVertices() - 可视化边缘顶点 - DebugPrintVertexAttributes() - 输出顶点属性统计信息 - Task 12: 性能优化和参数调优 - 添加 bEnableAdaptiveOptimization 参数 - 添加 MinSmoothingInterval 参数 - 添加 LastHammerImpactTime 追踪 - 在OnHammerImpact中应用自适应优化逻辑 Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
