fix: improve fuzzy matching for tracks with special formatting

- Lower matching threshold from 60 to 50 for more lenient matching
- Add fallback to trust provider's top result when artist matches well (>=70)
- Helps match tracks with parentheses, brackets, and stylized titles like 'PiLlOwT4lK'
- Provider search already does fuzzy matching, so trust it when artist is correct
