[FEATURE] Introduce ProcessorSkipper for conditional processor execution

- ✨ Added ProcessorSkipper class to manage processor skipping logic.
- 🔧 Integrated ProcessorSkipper into FractorRunner and AllowedFileExtensionsResolver to conditionally skip processors based on configuration.
- 📜 Updated SkipConfiguration to support processor skipping configurations.
