//! Core memory engine — storage, search, relations, and maintenance.
//!
//! This module contains the write path ([`store`]), read path ([`search`]),
//! entity graph ([`relations`]), deletion ([`forget`]), statistics ([`stats`]),
//! and lifecycle management ([`maintenance`]). Type definitions live in [`types`].
