//! Custom wa-rs storage backend using KylinBot's rusqlite
//!
//! This module implements all 4 wa-rs storage traits using rusqlite directly,
//! avoiding the Diesel/libsqlite3-sys dependency conflict from wa-rs-sqlite-storage.
//!
//! # Traits Implemented
//!
//! - [`SignalStore`]: Signal protocol cryptographic operations
//! - [`AppSyncStore`]: WhatsApp app state synchronization
//! - [`ProtocolStore`]: WhatsApp Web protocol alignment
//! - [`DeviceStore`]: Device persistence operations
