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

"""Hover Event Manager with Debounce Logic.
|
||||
|
||||
This module provides a robust hover event management system for the track list,
|
||||
implementing debouncing to prevent UI flickering and excessive updates during
|
||||
rapid mouse movements.
|
||||
|
||||
The HoverManager intercepts mouse movement events and triggers callbacks only
|
||||
after the mouse has remained stationary over an item for a configurable delay.
|
||||
|
||||
Architecture:
|
||||
- HoverManager: Main coordinator with debounce timer
|
||||
- Event filter for capturing mouse movements
|
||||
- Signal-based callbacks for decoupled communication
|
||||
|
||||
Performance:
|
||||
- Configurable debounce delay (default: 350ms)
|
||||
- Automatic cleanup of pending timers
|
||||
- Thread-safe signal emissions
