Warry 4f2eaececc 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

- 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:

  - "View Download History..." - Opens history dialog
  - "Prevent Duplicate Downloads" - Toggle with persistence
- New Download History dialog with:
