Module extensions 

Generic extension storage for [AimDbBuilder] and [AimDb].

External crates store typed state here during builder configuration and retrieve it during record setup or at query time. This is the hook mechanism used by aimdb-persistence — and any other crate that needs to attach data to the builder or the live database without modifying aimdb-core.

Example

// Storing a value (e.g. from an external "with_persistence" builder ext):
builder.extensions_mut().insert(MyState { ... });

// Retrieving it from a RecordRegistrar closure:
let state = reg.extensions().get::<MyState>().expect("MyState not configured");

// Retrieving it from a live AimDb handle (query time):
let state = db.extensions().get::<MyState>().expect("MyState not configured");
