docs: unify documentation and streamline code comments

- Translated project documentation (LEARNING-JOURNEY, CONTRIBUTORS, AI_DISCLOSURE) to English for better accessibility.
- Standardized internal code documentation by converting XML-doc blocks to standard comment format.
- Cleaned up inline comments and removed redundant versioning metadata across the codebase.
- Refactored non-functional text elements to improve readability and maintain a consistent style.
