Improve robustness of final file detection after download

Browse Source 
Enhanced the logic for finding the final downloaded file by always searching for the most recent video or audio file in the download directory and its subdirectories. This approach handles various post-processing scenarios such as merging, remuxing, and subtitle embedding, ensuring the correct file is identified even if the tracked path is invalid or missing.
