- SaveMergedLoRA now writes safetensors metadata (source LoRAs, merge
settings, architecture) plus optional user prompt/description
- SaveTunerData accepts optional prompt/description, embeds in JSON
- LoadTunerData outputs prompt, description, and metadata_info strings
- AutoTuner records source_loras in tuner_data for provenance
- New LoRAMetadataReader passthrough node extracts metadata from any
safetensors LoRA in a stack (prompt, description, merge info)
- LoRAStack attaches file metadata at load time; _normalize_stack
preserves it through both tuple and dict paths
- Graceful degradation: missing metadata produces empty strings
