- Add depth window approach instead of single extreme value selection
- Implement voting mechanism: components need visibility in 8%+ directions
- Multi-level confidence based on visibility ratio (25%/8% thresholds)
- Calculate adaptive depth window: max(0.2% diagonal, 15% median thickness)
- Add top-K fallback to ensure minimum visible components
- Fix compilation errors: add unordered_map header, fix C++17 syntax
This reduces over-aggressive deletion from 90% to more reasonable levels by
properly identifying partially visible components in second/third layers.
