//! CLI Integration Tests

//! These tests spawn the `pmat` binary as a subprocess. They are ignored by default
//! because they depend on a built binary being present and are non-deterministic
//! under parallel test load (resource contention causes spurious failures).
//!
//! Run explicitly with: `cargo test --lib -- cli_integration_tests --ignored`
