🧠 Improve answer analysis to handle mixed responses

- Enhanced detection logic to distinguish between pure 'I don't know' and thoughtful hypotheses
- When child says 'I don't know but maybe it's temperature', now treats as substantial thinking, not ignorance
- Added detection for substantive content: hypotheses, questions, specific topics (temperature, weather)
- Updated server to provide Socratic follow-up questions for thoughtful answers instead of just validation
- Improved fallback responses to be contextually aware of specific topics mentioned
- Better handling of answers that show reasoning even when prefixed with 'I don't know'

Now 'das weis ich nicht. hat es etwas mit der temperatur zu tun?' gets proper Socratic questioning about temperature instead of generic encouragement.
