Make more precise

[HarutakaMatsumoto]

This is more precise, but is slower.

Pull Request Overview

This PR improves the precision of distance calculations in the geometric measurement algorithm, implementing additional safeguards and refinements to prevent numerical instabilities. While the changes make the algorithm more accurate, they come with a performance trade-off as mentioned in the description.

• Added bounds checking and fallback mechanisms to prevent numerical overflow/underflow
• Refactored the algorithm flow to include state restoration capabilities
• Added degeneracy checks for cross product operations to handle edge cases
