feat(hover): add track details preview on hover + fix all ruff violations

Implement comprehensive track information display on hover and resolve all
code quality issues to achieve complete ruff compliance.

MAJOR FEATURES:
- Track details preview on hover with rich metadata display
- Async BPM fetching with loading indicator
- Enhanced metadata utilities with fuzzy matching
- TIDAL API extras integration

FILES MODIFIED: 15+ files (core, UI, tests, docs)

RUFF COMPLIANCE: 0 errors (89+ violations resolved)
- Fixed E999 syntax error in metadata_utils.py
- Refactored 10+ complex functions (C901)
- Updated error handling (S110, S112, SIM105)
- Modernized type hints (UP038)
- Fixed naming conflicts (A001, F811)

BUG FIXES:
- Added missing _on_update_cover() method (11 test failures)
- Fixed BPM display and async loading
- Improved thread safety

TESTING: 30 passed, 1 skipped
DOCUMENTATION: Windows PowerShell support, tox troubleshooting
