- Added a new proposal for boundary smoothing in the weight cutout process, differentiating between Split edges and Outline smoothing requirements. - Introduced a new capability `cutout-boundary-smoothing` to control smoothing strength and default values. - Updated specifications to define the behavior of boundary-specific smoothing strength and default settings. - Created tasks to verify the implementation of boundary behavior and asset updates. - Developed comprehensive tests for depth symmetry and normal scaling to ensure expected behavior and performance. - Introduced new attributes for normal mapping to facilitate persistent face attributes sharing between depth symmetry and image materials. - Built a new node group for O Image Depth Symmetry, integrating the new smoothing capabilities and ensuring compatibility with existing workflows.

Why
现有 Depth Balloon 始终向原 Cutout 剪影收拢。用户需要另一种对称形体：轮廓随深度投射变化，两侧围绕固定 XY 平面对称，并通过直壁补成完整网格。小车独立实验已验证效果；直接构建版本在保留相同边界平滑时，比布尔原型约快 5.7–7.1 倍。
What Changes
- 将功能命名为 Depth Symmetry，节点组命名为
O Image Depth Symmetry，提供Balloon / Projected两种模式。 Balloon保持原有行为；Projected直接采样深度、调整投射方向、删除越界面、镜像并补直壁。- Lasso 默认使用
Balloon，Polyline 默认使用Projected；创建后仍可通过 Mode 切换。与现有 Depth Cutout 的Lasso → Balloon / Polyline → Shell对应。 - 正面保持在局部
Z≥0；开启 Double Sided 后，两侧关于局部Z=0对称，外边界沿 Z 轴连接，形成封闭网格。 - 复用公共采样、清理、平滑和节点接口构建函数，新模式独立构建，不使用布尔或依赖 Depth Plane、Depth Cutout 节点组。
- BREAKING：将节点资产名、Shape 标识
DEPTH_BALLOON、构建模块及相关代码名称统一为 Depth Symmetry，不保留旧名转发或兼容资产。
