// Phase 143 P0: loop(true) + if + break minimal test
//
// Pattern: loop(true) { if(cond_pure) break }
// Expected: exit code 7 (cond is true immediately, break, return 7)
//
// This test verifies:
// - loop(true) is recognized
// - Pure condition (flag == 1) is lowerable
// - Break exits loop immediately
// - Return after loop is processed normally
