jpmschweitzerandClaude Opus 4.6 37ba7042a8 data(atlas): add missing planets and asteroid belts to 40 proposals
Systems below the minimum planet count for their spectral class now
have outer ice/frozen worlds added. Systems missing asteroid belts
have a sparse outer belt inserted. Orbit indices renumbered to stay
monotonic after insertions.

Remaining 5 verify errors are unnamed stations/bodies (content decisions).
