//! Storage abstraction layer for Arbiter.
//!
//! Provides async traits ([`AgentStore`], [`SessionStore`], [`DelegationStore`])
//! with pluggable backends. The default backend is in-memory; the `sqlite`
//! feature enables a WAL-mode SQLite backend with auto-migration.
//!
//! REQ-007: Storage behind async trait; swappable backends.
//! Design decision: SQLite chosen, designed for swappable.
