Parakeet-redux models are now in parakeet.cpp

An X post from @mudler_it says all Parakeet-redux models are now in parakeet.cpp and that parakeet can be used as a standalone voice activity detector. The same post calls Parakeet-redux “a really interesting beast” and claims its extracted VAD head has better recall than Silero, but the supplied material does not include independent benchmark or release-note detail.
