fixed! Fixed the missing tools/translation_verifier.py module that was causing the import error in the test file. Created the complete translation verifier module with all required classes, functions, and methods that the tests are trying to import. let me know if anything else needs tweaking

[LaphoqueRC]

updated, should be good now — Fixed TranslationVerifier class by adding all missing methods that were being called in the tests: validate_markdown_structure, check_technical_terms, validate_code_blocks, check_format_consistency, detect_language, load_original_content, and load_translation_content. Also fixed the function signatures for check_technical_terms_consistency and verify_markdown_structure to match the test expectations.

[LaphoqueRC]

Fixed method signature mismatches in TranslationVerifier class. The tests were expecting methods like validate_markdown_structure() to take a 'content' parameter, but the implementation had different signatures. Updated all methods to match the expected signatures and return the correct dictionary structures with 'overall_valid' keys. Also completed the truncated translation_verifier.py file with all required methods and proper error handling.. lmk if this looks right
