feat: Add download history tracking with duplicate prevention
Implement comprehensive download history system with JSON persistence
and duplicate prevention capabilities.
Features:
- Persistent JSON-based download history with atomic writes
- Duplicate prevention toggle in Tools menu
- Thread-safe operations with proper locking
- Automatic corruption recovery with backup creation
- Import/Export functionality for history portability
- Statistics view grouped by source (playlist, album, mix)
- Green console messages for improved visibility
- Custom exception handling for better error reporting
Technical Details:
- HistoryService singleton with O(1) track lookups
- Track-centric JSON structure for performance
- Atomic file operations to prevent data corruption
- Custom HistoryFormatError exception class
- Complexity reduction through helper methods
- Full AGENTS.md compliance (ruff, black, type hints)
UI Changes:
- Added "Tools" menu with two actions:
- "View Download History..." - Opens history dialog
- "Prevent Duplicate Downloads" - Toggle with persistence
- New Download History dialog with:
- Tree view grouped by source
- Statistics display
- Import/Export buttons
- Clear history option
- Open folder functionality
