refactor: Better prompt engineering for witty and engaging responses

[shettydev]

Priority: Medium

The first response during conversations should be more engaging, witty, and memorable while maintaining the Socratic method's educational value.

Requirements

• Create a library of witty opening responses categorized by query type
• Implement personality injection that maintains professionalism (shouldn't go too overboard)
• Add contextual humor that's appropriate for different scenarios (basically not too dark)
• Ensure responses remain educational and thought-provoking
• Create fallback mechanisms for serious/sensitive topics
• A/B test different response styles

Acceptance Criteria

• First responses are more engaging and memorable (emphasis on the first)
• Wit is appropriate and doesn't overshadow educational content
• Responses maintain respect for all query types
• User feedback improves response quality over time
• Different personality styles are available based on user preference (optional)
