- Implemented AdjustExistingTrackDrift struct with execute method to modify drift scale of existing tracks in a project. - Added tests for adjusting drift scale, handling non-existent track IDs, and invalid scale values. - Updated MediaTrackInfo and AudioTrack entities to include drift_scale field. - Enhanced Project entity with needs_mkvmerge method to determine if mkvmerge is required based on drift scale. - Integrated drift scale adjustments into existing track list UI, allowing users to modify drift values. - Updated various use cases and UI components to support drift scale functionality, including add audio/subtitle forms and batch processing. - Implemented mkvmerge availability check and integrated it into the application workflow for conditional processing.
