High-level join planning API that wraps hash join execution.

This crate exposes shared types (JoinKey, JoinType, JoinOptions) used by the planner and runtime to negotiate join configuration. Execution currently routes through the hash join implementation in hash_join_stream, with a placeholder for alternate algorithms when they land.

LLKV Join

llkv-join implements relational join algorithms for the LLKV database toolkit.

This crate is not intended for direct standalone use.
