- Introduced a new RecipeParserFactory to streamline the parsing of recipe metadata from user comments, supporting multiple formats. - Removed legacy metadata extraction logic from RecipeRoutes, delegating responsibilities to the new parser classes. - Enhanced error handling for cases where no valid parser is found, ensuring graceful responses. - Updated the RecipeScanner to improve the handling of LoRA metadata and reduce logging verbosity for better performance.
