🚀 feat(ci): add automated release generation with version tagging

- Add automatic timestamp-based version generation (v2025.MM.DD.HHMM format)
- Implement automatic GitHub release creation when changes are committed
- Generate comprehensive release notes with recent commit history
- Include API documentation links and usage instructions in releases
- Add git tag creation and push functionality
- Convert all release notes and comments to English
- Only create releases when actual code changes are detected

This enhancement automates the release process, providing better tracking
of API data updates and improved user experience with detailed release
documentation.
