🔧 MAJOR FIX: Proper Language Detection & Relevant Chart Generation

LANGUAGE FIXES:
✅ English queries now respond in English only (no Hindi mixing)
✅ Added language detection override for query-based responses
✅ Removed unnecessary bilingual formatting for English queries
✅ Fixed Rajasthan formatting to respect query language

CHART RELEVANCE FIXES:
✅ Charts now analyze actual query content instead of showing generic data
✅ Different chart types for different queries:
- 'pension rules' → Rule Compliance Analysis
- 'increment' → Increment Trend Analysis
- 'impact' → Policy Impact Analysis
- Generic → Overview Analysis
✅ Meaningful chart titles and data points

USER EXPERIENCE IMPROVEMENTS:
✅ English queries = English responses (clean, professional)
✅ Hindi queries = Hindi responses (bilingual when needed)
✅ Charts show relevant data based on actual user question
✅ No more generic 'sample data' in visualizations

Query 'show impact of pension rules' will now:
- Respond in English only
- Show Rule Compliance Analysis chart
- Provide relevant pension rule information

Ready for testing! 🎯
