Pasukhin Dmitry 3270746444 Foundation Classes - Improve numerical robustness and evaluation efficiency (#1585)
- Stabilize B-spline interpolation and derivative evaluation on uneven knots.
- Add local surface span selection with periodic seam derivative handling.
- Optimize polynomial and rational surface cache first derivatives.
- Consolidate torus evaluators and preserve small components near singularities.
- Fix thin triangle projection and support independent optional BVH outputs.
- Preserve Bezier cusps when adjacent tangents have opposite directions.
- Apply Householder reflectors directly to right-hand sides without forming Q.
- Reuse QR and SVD decompositions and retain small modes under regularization.
- Make Newton convergence and PSO stagnation independent of objective scale.
- Add strict PSO domain handling and optimize particle restart selection.
- Use relative Laguerre residual checks to reject inaccurate roots.
- Add exact component restoration for directions, frames and transformations.
- Fix point mirror inversion and simplify location chain operations.
- Honor default thread pool launch limits in OSD_Parallel.
- Add flat map storage accounting and Precision::IsFinite.
- Default GUID copy assignment and extend GTest regression coverage.
