- 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.
Net change: +368 lines
- Add tomlc17 library as git submodule
- Update Makefile to build tomlc17.c with C compiler
- Replace config_loader.cpp with TOML-based implementation
- Add helper functions for parsing TOML tables (position, color)
- Convert all 5 config files from .txt to .toml format:
* configs/solar_system.toml - full solar system with planets and moons
* configs/example_binary_star.toml - binary star system
* configs/test_simple.toml - various orbit types for testing
* tests/configs/earth_circular.toml - Earth orbit test
* tests/configs/mars_circular.toml - Mars orbit test
- Update all test files to reference .toml extensions
- Remove old .txt config files (maintain compatibility)
- Support both INT64 and FP64 TOML values (tomlc17 type flexibility)
- All automated tests pass with new TOML format
