feat: add direct links download functionality
- Implemented a new task type for handling direct links downloads. - Added command handler for downloading multiple links via /dl command. - Introduced progress tracking for direct link downloads. - Enhanced filename parsing to support various encoding scenarios. - Updated enums to include direct links as a task type. - Refactored existing task structures to accommodate new functionality. - Improved error handling and logging throughout the download process.
