Subject: [PATCH] Detect private/sign-in yt-dlp errors

Update AnalysisThread error handling to detect yt-dlp stderr containing "Private video" or "Sign in". For those cases, emit a localized errors.private_video message and log a specific private-video error; otherwise preserve the existing generic ytdlp_failed behavior. Playlist visibility signals and early return remain unchanged.
