- Changed warning logs to debug logs in CivitaiClient and RecipeScanner for better log granularity. - Updated the mapper registration function name for clarity and adjusted related logging messages. - Enhanced extension loading process to automatically register mappers from NODE_MAPPERS_EXT, improving modularity and maintainability.
