Title: Add HTML render config and update gitignore rules

Key features implemented:
- Added html-render-config.json with root directory, index file, and static prefix settings for website rendering
- Updated .gitignore to exclude Python cache files, compiled files, logs, and environment files while removing old project-specific entries

The changes improve project configuration management and clean up version control exclusions for better development workflow.
