Follow-up to #2958. MOSS-TTS-Nano was authored before the schema refactor
and still shipped as a legacy stage_configs yaml; this aligns it with the
same layout the 5 migrated TTS models now use.
- vllm_omni/model_executor/models/moss_tts_nano/pipeline.py declares
MOSS_TTS_NANO_PIPELINE (single LLM_AR stage, owns_tokenizer, audio
output, stop_token_ids=[2] as a hard EOS backstop).
- vllm_omni/deploy/moss_tts_nano.yaml holds runtime knobs (max_num_seqs,
gpu_memory_utilization, enforce_eager, default_sampling_params,
skip_mm_profiling); trust_remote_code stays at deploy top-level.
- vllm_omni/config/pipeline_registry.py registers the entry so the lazy
registry can resolve it.
- moss_tts_nano/__init__.py exports MossTTSNanoForGeneration (VoxCPM2 pattern).
- Removed vllm_omni/model_executor/stage_configs/moss_tts_nano.yaml.
Examples, shell scripts, READMEs, and buildkite-invoked tests are
updated to use `vllm serve <model> --omni` / `--deploy-config`
(auto-load kicks in; no --stage-configs-path or --trust-remote-code).

The upstream inference_stream() API has no voice/spk parameter;
voice preset selection is not yet wired into the call. Remove the
dead assignment to silence ruff F841.

Integrates OpenMOSS-Team/MOSS-TTS-Nano (0.1B) as a single
GPUGenerationWorker stage. Both the AR LM and MOSS-Audio-Tokenizer-Nano
codec run inside MossTTSNanoForGeneration.forward(), removing the need for
an inter-stage connector.
Key design choices:
- Weights loaded in load_weights() not __init__ (avoids pre-CUDA alloc)
- trust_remote_code delegates to upstream HF model classes
- codec path read from config.audio_tokenizer_pretrained_name_or_path
- inference_stream() collects progressive audio chunks for low latency
- 48 kHz stereo output; voice clone + continuation modes supported
