Subject: [PATCH] fix: Optimize knowledge limit handling for first questions
 and comprehensive explanations

- Fix knowledge limit detection for immediate 'keine ahnung' responses
- Increase token limit to 350 for complete explanations without truncation
- Improve explanation structure to 3-4 sentences for better comprehension
- Add special case handling for first question knowledge limits
- Enhance system prompts with concrete examples for consistency
- Ensure smooth progression through all fundamentals

Testing confirmed:
- All question types work with fundamentals-first approach
- Knowledge limit detection triggers appropriately
- Complete explanations with proper transitions
- No hardcoded responses - fully AI-driven
- System handles diverse topics dynamically

System is now production-ready with robust educational methodology.
