// Simplified TDD Test Suite for src/quality/formatter.rs
// Target: Basic formatter functionality with 95%+ coverage
// Sprint 79: Push Coverage to 75%
//
// Quality Standards:
// - TDD methodology: Test-first development
// - Cyclomatic complexity ≤10 for all test functions
// - Zero SATD comments
