sqry-cli 10.0.4

//! CLI integration tests for Vue relation queries
//!
//! Tests that relation queries work end-to-end through the CLI for Vue:
//! - Callers queries (function calls in script section)
//! - Callees queries (what a function calls)
//! - Exports queries (exported functions, components)
//! - Imports queries (import statements in script section)
