feat: consolidate env config and add deployment files

- Add debug_font_path, demo_docs_dir, e2e_api_base_url to config.py
- Fix hardcoded paths in pp_structure_debug.py, create_demo_images.py
- Fix hardcoded paths in test files
- Update .env.example with new configuration options
- Update .gitignore to exclude AI development files (.claude/, openspec/, AGENTS.md, CLAUDE.md)
- Add production startup script (start-prod.sh)
- Add README.md with project documentation
- Add 1panel Docker deployment files (docker-compose.yml, Dockerfiles, nginx.conf)
