fraiseql-cli 2.2.0

#![allow(clippy::unwrap_used)] // Reason: test code, panics are acceptable
//! Integration tests for `fraiseql analyze`.
//!
//! Invokes the real CLI binary and inspects exit codes and JSON output.
//! No database required — `analyze` works purely on the schema file.
//!
//! **Execution engine:** none (CLI binary only)
//! **Infrastructure:** none (filesystem only)
//! **Parallelism:** safe
