//! Key-Value Store functionality
//!
//! This module provides a simple key-value store with encryption support.
//! 
//! The implementation uses different backends depending on the platform:
//! - For WebAssembly: IndexedDB through the `IndexedDbStore` type
//! - For native platforms: SlateDB through the `SlateDbStore` type
//!
//! All implementations share the same interface defined by the `KVStore` trait.
