Task 306: Cross-validate Supplementary Rust Modules

Status: DONE

Description

Add independent Python cross-validation for supplementary Rust modules that are currently

only tested internally:

1. relativistic.rs: Lorentz factor, time dilation, relativistic rocket equation, brachistochrone proper time
2. attitude.rs: Miss distance, pointing accuracy, flip maneuver torque, gravity gradient torque
3. plasmoid.rs: Magnetic/ram pressure, velocity perturbation, miss distance from encounter

These modules have internal Rust tests but no external cross-validation against

independent implementations (unlike the orbital mechanics core which has scipy/poliastro validation).

Approach

• Add export of key values from these modules in cross_validation_export.rs
• Create cross_validation/validate_supplementary.py with independent Python implementations
• Integrate into run.sh
