- Enhanced 'I don't know' detection to include German variants (ich weiß es nicht, warum, etc.)
- When child says 'I don't know', system now directly provides Socratic guidance instead of asking for deeper exploration
- Removed redundant phrases like 'Danke, dass du deine Gedanken geteilt hast' for obvious interactions
- Improved fallback responses to be more concise and natural ('Perfekt! Lass uns das gemeinsam herausfinden.')
- Updated both chat mode and step-by-step mode to have consistent behavior
- System now automatically continues to next question for 'don't know' responses, only shows choice buttons for substantial answers
This creates a smoother, more natural learning flow without interrupting the Socratic discovery process.
