New atlas subcommand: sync-wiki generates a Celestial Bodies section
in wiki pages from DB body/station data. All fields rendered: orbit,
ID, name, type, inhabited, population, mass, gravity, atmosphere,
biome, hydrosphere, economy, settlement pattern, industrial corridor.
Stations table includes docking class, governance, gate flag, districts.
Moons render indented under their parent body (↳ notation).
Section is idempotent — re-running overwrites the existing section.
DB is source of truth, wiki is generated output. No import direction.
