DownloadVideo already handles the Panopto Login.aspx canvas auth form correctly through its multi-step form submission logic. The real fix for ExternalUrl Panopto folder links was the URL normalization (List.aspx?folderID= → List.aspx#folderID="...") already in DownloadVideo. Remove DownloadExternalPanoptoURL (dead code) and all debug prints. Update README with -vo flag documentation.
