Remove yt-dlp Python package usage; use binary only

Refactored all modules to remove dependency on the yt-dlp Python package, switching to subprocess calls to the yt-dlp binary for all extraction and update operations. Update logic now exclusively manages the app's own yt-dlp binary and no longer supports pip-based updates. Simplified format/audio detection and thumbnail extraction to use CLI heuristics and subprocess output. This improves reliability and avoids Python package conflicts.
