//! CLI tests for `wj lint` - Rust leakage linter
//!
//! Validates that the linter correctly:
//! - Passes clean files
//! - Detects W0001-W0004 violations
//! - Fails with --strict when warnings present
//!
//! Uses library API directly (windjammer::linter) since wj binary
//! requires full CLI feature build.
