In SkyQueryEnvironment, rewrite queries using the semantics-preserving transformation 'rdeps(<sky_query_environment_universe_scope>, T, depth)' -> 'allrdeps(T, depth)'.

SkyQueryEnvironment can evaluate such allrdeps queries much more efficiently since it doesn't need to bother filtering out targets outside of universe, meaning it doesn't need to have all targets in the universe in memory at the same time.
