feat: enhance intent classification with advanced confidence scoring and keyword matching

- Improve intent confidence calculation with more nuanced scoring
- Add comprehensive keyword and pattern matching for better intent detection
- Refactor confidence calculation to handle various input scenarios
- Implement more aggressive boosting for specific action keywords
- Adjust parameter extraction logic for more robust intent parsing
