PXL8D 8722ae61dd Initial commit: MetaMan universal metadata management system
- Universal metadata extraction and conversion across AI platforms
- Support for A1111, ComfyUI, Civitai, Forge, Tensor.AI, Leonardo.AI
- Template-driven architecture for easy platform extension
- Model dependency resolution with download URLs
- Custom 'meta' PNG chunk standard for cross-platform compatibility
- Comprehensive validation and testing system
