- Created tests/test_moon_orbits.cpp with 4 test cases:
* Moon orbital stability around Earth
* Galilean moons orbital stability around Jupiter
* Titan orbital stability around Saturn
* Combined solar system parent stability
- Enhanced test_utilities.h/cpp:
* Added min_time_days field to OrbitTracker
* Added create_orbit_tracker_with_min_time() for short-period orbits
- Fixed parent indexes in tests/configs/solar_system.toml:
* Moon: parent 3 (Mars) → 2 (Earth)
* Io/Europa/Ganymede/Callisto: parent 5 (Saturn) → 4 (Jupiter)
* Titan: parent 6 (Uranus) → 5 (Saturn)
- Updated semi_major_axis for moons to actual orbital distances
Tests reveal need for hierarchical orbit physics implementation.
