Added ACE Step v1 3.5B model for state-of-the-art music generation:
- 15x faster than LLM baselines with superior structural coherence
- Supports 19 languages (en, zh, ja, ko, fr, es, de, it, pt, ru + 9 more)
- Voice cloning, lyric alignment, and multi-genre capabilities

Changes:
- Added ACE Step models to models_huggingface.yaml (checkpoint + Chinese RAP LoRA)
- Added ComfyUI_ACE-Step custom node to arty.yml with installation script
- Created 4 comprehensive workflows in comfyui/workflows/text-to-music/:
  * acestep-simple-t2m-v1.json - Basic 60s text-to-music generation
  * acestep-multilang-t2m-v1.json - 19-language music generation
  * acestep-remix-m2m-v1.json - Music-to-music remixing with style transfer
  * acestep-chinese-rap-v1.json - Chinese hip-hop with specialized LoRA
