Enhance mutation capabilities by adding three new types: encoding_attacks, context_manipulation, and length_extremes. Update configuration and documentation to reflect the addition of these types, including their weights and descriptions. Revise README.md, API_SPECIFICATION.md, CONFIGURATION_GUIDE.md, and other relevant documents to provide comprehensive coverage of the new mutation strategies and their applications. Ensure all tests are updated to validate the new mutation types.
