Fix step-by-step question parsing and improve AI prompts

FIXED ISSUES:
- AI was giving introductions instead of direct numbered questions
- Parser wasn't correctly extracting numbered questions
- Missing detailed debugging for response parsing

IMPROVEMENTS:
- Enhanced prompts to explicitly request ONLY numbered questions
- Improved parsing function with detailed logging
- Better numbered question detection with regex
- Fallback question detection for non-numbered items
- Comprehensive debugging output for troubleshooting

RESULT:
- Step-by-step mode now properly displays 3-4 Socratic questions
- Questions guide children through discovery process
- Better instruction following with GPT-4o-mini model
