Fix multi-format documentation CI: Improve error handling and robustness
Major improvements to documentation build process: 🔧 Enhanced build-docs.sh script: - Add graceful error handling for failed HTML/Sphinx builds - Create build directories even when Sphinx fails - Generate fallback HTML page when build fails - Improve packaging function to check directory existence - Better status reporting and exit codes 📝 Improved Sphinx configuration (conf.py): - Dynamic extension loading with try/catch for optional dependencies - Core vs optional extension separation - Better error messages for missing dependencies - More robust configuration handling 🚀 Updated CI workflow (python-docs.yml): - Enhanced error handling in build step - Improved documentation packaging logic - Conditional artifact uploads based on file existence - Better failure recovery and partial build support 📁 Repository maintenance: - Add documentation-output/ to .gitignore - Prevent accidental commit of generated documentation files These changes ensure the documentation CI: 1. Handles missing dependencies gracefully 2. Creates useful output even when builds partially fail 3. Provides clear error messages and fallback content 4. Maintains CI stability with better error handling
