Extend config format to support both circular and eccentric orbits using
eccentricity and semi-major axis parameters. All bodies now use the same
format: e=0 for circular orbits, e>0 for eccentric orbits.
Velocity calculation uses vis-viva equation for all cases. Add example
comet with highly eccentric orbit (e=0.7) to test configuration.

Physics Updates (bodies.cpp):
- Root bodies now apply gravitational forces to each other
- Physics loop split into: root body updates, then child body updates
- Enables binary/multiple star systems to orbit their barycenter
Config Loader Updates (config_loader.cpp):
- Detect multiple root bodies (parent_index = -1)
- Calculate system barycenter (center of mass)
- Set initial velocities for root bodies to orbit barycenter
- Add debug output showing barycenter and orbital speeds
Binary star systems now work correctly with both stars
orbiting their common center of mass.
