LuqP2 f6bdd59fdc Add workflow auto-extraction and multi-format metadata saving 
Auto-detect sampler/model/vae/prompts/loras with concrete node lists and multi-sampler heuristic
Switch to None sentinels for overrides and add filename placeholders + sanitization
Add JPEG/WebP metadata via EXIF (piexif) and update README/docs

LuqP2 238e458de6 feat: Implement MetaHub Save Image node for ComfyUI 
Complete implementation of advanced image saving node with dual metadata:
- A1111/Civitai compatible metadata (tEXt chunk "parameters")
- Image MetaHub metadata (iTXt chunk "imagemetahub_data")
- Auto-detection of LoRAs from workflow (UI and API formats)
- SHA256 hash calculation (AutoV2/Civitai format) with caching
- Graceful degradation (never interrupts generation)
- IMH Pro fields support (user_tags, notes, project_name)
- Auto-increment filenames with customizable output paths

Files added:
- metahub_save_node.py: Main node class with INPUT_TYPES
- metadata_utils.py: Hash calculation, metadata formatting, PNG injection
- __init__.py: Node registration for ComfyUI
- requirements.txt: Dependencies (Pillow, numpy)
- README.md: Installation and usage documentation

100% compatible with Image MetaHub comfyUIParser.ts specification.
