// The run cases (testRunCommand, testRunCommandInvalid, testRunGuessNameFromDirSanitizesDir,
// testInteractiveRun) drive the full command via ApplicationTester / initTempComposer, which
// does not exist here; they remain reason'd-ignore. The unit-style cases call the helper
// methods directly via `__`-prefixed test-only wrappers.
