Crate exo_dag_db_retrieval 

Retrieval, routing, and context packet selection for DAG DB.

Facade removal is complete; this crate owns graph context selection, hybrid retrieval, catalog routing, packet output, and read-side query/view helpers. Downstream compatibility uses explicit bridges such as exo_api::dagdb.

Re-exports

pub use graph_context_selection::GraphContextMemoryCandidate;

pub use graph_context_selection::GraphContextSelectionState;

pub use graph_context_selection::select_graph_context;
