🚀 SMART RESULT RANKING (Zero Overhead)
- File importance boost: README, main, config files get 20% boost
- Recency boost: Files modified in last week get 10% boost
- Content quality boost: Functions/classes get 10%, structured content gets 2%
- Quality penalties: Very short content gets 10% penalty
- All boosts are cumulative for maximum quality improvement
- Zero latency overhead - only uses existing result data
