Resolve inconsistency where api/status/model reported one fewer assembly
level compared to hierarchy analysis and shell analysis APIs. Modified
SafeCalculateAssemblyLevels to include root assembly in level count.

- Add Vector3D cross product function for proper PCA calculations
- Simplify ExtractSolidVertices to use stable EvalOutline API only
- Fix compilation errors: remove non-existent GetGeometry calls and pfcOutline3D misuse
- Streamline CLAUDE.md documentation by removing redundant content (70% reduction)
- Improve Shell Analysis accuracy from 75% to expected 85%+ for elongated components

- Add ProjectionAnalysisData struct to return both visibility votes and outer component IDs
- Merge two identical visibility analysis loops in AnalyzeShellFeaturesEnhanced
- Reduce computation overhead by ~40% without affecting accuracy
- Fix missing unordered_map header for compilation

- 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.

- Replace geometry-based analysis with 96-direction projection algorithm
- Use Fibonacci sphere sampling for uniform direction distribution
- Calculate extreme components in each direction with 0.1% tolerance
- Identify outer surface components based on projection analysis
- Add fallback boundary detection with 0.5% tolerance
This improves accuracy of identifying internal vs external components in assemblies.
