Removed acestep-simple-t2m-v1.json as the official Comfy-Org workflows provide better quality:
- acestep-official-t2m-v1.json - Advanced T2M with specialized nodes
- acestep-m2m-editing-v1.json - Music-to-music editing capability

Removed 3 empty placeholder workflows that only contained metadata:
- acestep-multilang-t2m-v1.json
- acestep-remix-m2m-v1.json
- acestep-chinese-rap-v1.json
Kept only the functional workflow:
- acestep-simple-t2m-v1.json (6 nodes, fully operational)
Users can use the simple workflow and modify the prompt for different use cases:
- Multi-language: prefix lyrics with language tags like [zh], [ja], [ko]
- Remixing: load audio input and adjust denoise strength (0.1-0.7)
- Chinese RAP: use Chinese RAP LoRA with strength 0.8-1.0

Removed diffrhythm-random-generation-v1.json as it's no longer needed.
Keeping only the essential DiffRhythm workflows:
- simple text-to-music (95s)
- full-length generation (4m45s)
- reference-based style transfer

- Remove custom PivoineDiffRhythmRun wrapper node
- Add git patch file for ComfyUI_DiffRhythm __init__.py
- Patch adds LlamaConfig fix at import time
- Add arty script 'fix/diffrhythm-patch' to apply patch
- Revert all workflows to use original DiffRhythmRun
- Remove startup_patch.py and revert start.sh
This approach is cleaner and more maintainable than wrapping the node.
The patch directly fixes the tensor dimension mismatch (32 vs 64) in
DiffRhythm's rotary position embeddings by ensuring num_attention_heads
and num_key_value_heads are properly set based on hidden_size.

The parameters must match the diffrhythmgen() function signature order,
not the INPUT_TYPES order. The function has 'edit' as the first parameter.
Correct widgets_values order (11 parameters):
0: edit (boolean)
1: model (string)
2: style_prompt (string)
3: lyrics_or_edit_lyrics (string)
4: edit_segments (string)
5: odeint_method (enum)
6: steps (int)
7: cfg (int)
8: quality_or_speed (enum)
9: unload_model (boolean)
10: seed (int)
Note: style_audio_or_edit_song comes from input connection (not in widgets)
Note: chunked parameter is hidden (not in widgets)
Updated workflows:
- diffrhythm-simple-t2m-v1.json
- diffrhythm-random-generation-v1.json
- diffrhythm-reference-based-v1.json
- diffrhythm-full-length-t2m-v1.json

Fix "edit song, edit lyrics, edit segments must be provided" error by adding
the two missing parameters to all three DiffRhythm workflow files:
- diffrhythm-random-generation-v1.json
- diffrhythm-reference-based-v1.json
- diffrhythm-full-length-t2m-v1.json
Added empty string parameters at positions 9 and 10 in widgets_values array:
- edit_song: "" (empty when edit=false)
- edit_lyrics: "" (empty when edit=false)
The DiffRhythmRun node requires 12 parameters total, not 10. These workflows
use edit=false (no editing), so the edit parameters should be empty strings.

Sound Lab's Musicgen_ node outputs AUDIO format that is only compatible with Sound Lab nodes like AudioPlay, not the built-in ComfyUI audio nodes (SaveAudio/PreviewAudio).
SaveAudio was erroring on 'waveform' key - the AUDIO output from
Musicgen_ node has a different internal structure than what SaveAudio
expects. PreviewAudio is more compatible with Sound Lab's AUDIO format.
Files are still saved to ComfyUI output directory, just through
PreviewAudio instead of SaveAudio.

Fixed medium, small, and melody workflows:
- Replaced non-existent nodes with Musicgen_ from Sound Lab
- Added missing links arrays to connect nodes properly
- Updated all metadata and performance specs
Note: Melody workflow simplified to text-only as Sound Lab doesn't
currently support melody conditioning via audio input.

Changed from non-existent nodes to actual Sound Lab nodes:
- Replaced MusicGenLoader/MusicGenTextEncode/MusicGenSampler with Musicgen_
- Replaced custom SaveAudio with standard SaveAudio node
- Added missing links array to connect nodes
- All parameters: prompt, duration, guidance_scale, seed, device
Node is called "Musicgen_" (with underscore) from comfyui-sound-lab.

organization. Replace all hardcoded /workspace paths with relative paths
to make the configuration portable across different environments.
Changes:
- Move models/comfyui/ → comfyui/
- Move models/vllm/ → vllm/
- Remove models/ directory (empty)
- Update arty.yml: replace /workspace with environment variables
