Implemented clear_all_completed_downloads in YouTubeClient to remove completed, cancelled, errored, and aborted downloads from memory. Updated DownloadOrchestrator to call this method, ensuring both Soulseek and YouTube completed downloads are cleared.
Adjusts matching weights for YouTube sources to rely more on title and duration, adds a shutdown callback to the YouTube client to prevent new downloads during shutdown, and enhances post-processing to reliably resolve actual YouTube file paths. Improves error handling for file removal, ensures no new batch downloads start during shutdown, and refines download monitoring to trigger post-processing on completed YouTube downloads. Also increases YouTube download retries and improves logging for debugging.
Introduces a DownloadOrchestrator class to route downloads between Soulseek and YouTube based on user-configurable modes (Soulseek only, YouTube only, Hybrid with fallback). Updates web server and UI to support new download source settings, including hybrid mode options and YouTube confidence threshold. Refactors YouTube client for thread-safe download management and bot detection bypass. Ensures quality filtering is skipped for YouTube results and improves file matching and post-processing logic for YouTube downloads.
