Introduces a new scoring component for vertebral body (VBODY) rewards
to improve optimization accuracy. The update includes:
- Added `vbody_tensor` to `OptimizationContext` and scoring functions
to reward screw placement within the vertebral body.
- Enhanced `segment_spinous_process` with diagnostic capabilities to
detect spinous process absence (e.g., post-laminectomy).
- Improved `resample_img` to prevent physical boundary clipping and
handle interpolation more robustly for CT and label data.
- Implemented a metadata cache using TinyDB in the preprocessing
pipeline to skip low-resolution or insufficient scans efficiently.
- Added robust error handling for NFS-based file operations and
directory creation.
- Added new visualization tools for bone figures and level plotting.
refactor(imaging): improve segmentation and resampling precision
- Refactored `seg_bone` to support original resolution binary masks and
Signed Maurer Distance Maps (SMD) for more accurate boundary handling.
- Updated `resample_img` to use `ceil` for output size calculation to
ensure full physical coverage.
- Optimized `process_single_image` to utilize metadata for skipping
processing of invalid or low-quality scans.
