// aliasFlagValue handles a renamed sort flag whose old name is kept as a silent
// alias. It returns (oldValue, true) only when the old flag was explicitly used
// and the new one was not; otherwise ("", false) — meaning "no old flag, or both
// given (new wins), so use the new-flag logic". Pure function, no IO: callable
// from DryRun, Execute, and minimal test fixtures alike. Never prints anything.
