//! Basic unit tests for git context tracking
//!
//! This module contains basic unit tests for StepChanges struct and GitChangeTracker.
//! Additional comprehensive tests are organized in separate modules:
//!
//! - `git_context_uncommitted_tests` - Phase 1: Uncommitted Changes Detection
//! - `git_context_commit_tests` - Phase 2: Commit History Walking
//! - `git_context_diff_tests` - Phase 3: Diff Statistics and File Changes
//! - `git_context_test_utils` - Shared test utilities
