Accio: Bolt-on Query Federation

Summary: Accio decouples query federation from execution engines as a bolt-on middleware library. Its declarative interface enables join pushdown and query partitioning, delivering orders-of-magnitude gains across five engines without invasive modifications or maintenance.
