sqry-cli 6.0.21

//! CLI integration tests for Groovy relation queries
//!
//! Tests that relation queries work end-to-end through the CLI for Groovy:
//! - Callers queries (method calls, closures) - ✅ via GraphBuilder
//! - Callees queries (what a method calls) - ✅ via GraphBuilder
//! - Exports queries (classes, methods, closures) - ✅ via GraphBuilder
//! - Imports queries (import statements) - ✅ via GraphBuilder
