//! 3D Object Detection
//!
//! Provides PointPillar-style 3D object detection from point cloud data.
//! The pipeline consists of:
//! 1. **Voxelization** — discretize the point cloud into pillars/voxels
//! 2. **Backbone** — 2D CNN over bird's-eye-view features
//! 3. **Detection head** — anchor-based classification and bounding-box regression
