// qwen-tts.cpp : thin CLI wrapper around the Qwen3-TTS synthesis
// pipeline. Parses arguments, loads the talker + codec GGUFs, hands
// off to pipeline_tts_synthesize and writes the resulting waveform as
// a WAV file. All heavy lifting lives in src/pipeline-tts.cpp.
//
// Talker variants : 0.6B-Base / 0.6B-CustomVoice / 1.7B-Base /
// 1.7B-CustomVoice / 1.7B-VoiceDesign. The decoder path is selected
// from GGUF metadata at load time. The CLI surface mirrors the
// omnivoice.cpp tooling : kebab-case flags, --format wav16/wav24/wav32,
// -o '-' streams to stdout, --seed -1 means non deterministic, the
// utterance text comes from --text or stdin if --text is absent.
