fraiseql-core 2.2.0

//! Automatic Persisted Queries (APQ) infrastructure.
//!
//! APQ is a GraphQL optimization technique that allows clients to:
//! 1. Hash queries and send only the hash on subsequent requests
//! 2. Server responds with original query if not cached
//! 3. Reduces bandwidth for frequently-used queries
//!
//! # Security Considerations
//!
//! Cache keys MUST include variables to prevent data leakage between requests
//! with different variable values.
//!
//! # Module Contents
//!
//! - **hasher**: Query hashing with SHA-256 (pure Rust implementation)
//! - **storage**: APQ result storage and retrieval
//! - **metrics**: APQ performance metrics and monitoring
