- Move all configs from tests/configs/ to tests/
- Rename configs to match test filenames (test_NAME.toml)
- Remove unused configs (earth_mars_simple, simple_root_transition, interplanetary_transfer)
- Combine earth_circular and mars_circular into test_orbital_period.toml
- Duplicate earth_circular.toml as test_energy.toml
- Remove invalid parent test case from test_invalid_parent_assignment.cpp
- Update all test files to reference new config paths
- Delete tests/configs/ directory
- Create soi_transition.toml with Sun + Mars + SmallBody (3 bodies)
- Add test_soi_transition.cpp with 2 test cases:
* SOI transition from Sun to Mars (validates one-way transition)
* SOI radii calculation verification
- Use comet parameters (e=0.7, a=3.74e11) for Mars encounter
- Document hysteresis makes Mars -> Sun exit impossible
- Simpler than original 7-body test_comet_orbit.cpp
- All 3 SOI tests pass (12 assertions total)
