msvc-kit 0.2.10

//! Core unit tests for msvc-kit
//!
//! Note: Most tests have been split into separate files:
//! - version_tests.rs - Architecture and version tests
//! - downloader_tests.rs - Download options, preview, cache tests
//! - env_tests.rs - Environment and shell script tests
//! - config_tests.rs - Config and error tests
//! - bundle_tests.rs - Bundle layout and options tests
//! - reexports_tests.rs - Library re-export tests

// This file is kept for backwards compatibility and contains any tests
// that don't fit cleanly into the other categories.
