IMPROVEMENTS:
- Added detection for 'was hat...zu tun' (what does...have to do with), 'wo ist' (where is), 'wo sind' (where are)
- Added detection for 'wie funktioniert' (how does) and 'warum ist' (why is)
- Enhanced server-side definition prompts to handle location and relationship questions
- Added topic-specific fallback explanations for Earth/seasons/temperature questions
- Improved OpenAI prompt context for better definition responses
This ensures children asking direct questions like 'wo ist die erde?' or 'was hat die position damit zu tun?' get explanations instead of more Socratic questions.
