Add progress bar and filename display for downloads

Improvements:
- Shows current filename being downloaded prominently
- Displays file size before download starts
- Real-time progress bar with 50-character width
- Shows download speed (MB/s)
- Shows ETA (estimated time remaining)
- Visual progress with █ and ░ characters
- Final summary shows total size and average speed
- Clear success/failure messages with emojis

Example output:
  📥 Downloading: Video-Title
     Filename: Video-Title.mp4
     Size: 45.23 MB

     [████████████████████████░░░░░░░░░░░░░░░░] 50% | 2.34 MB/s | ETA: 10s

  ✅ Complete: 45.23 MB @ 2.34 MB/s

Users can now see exactly what's happening and know the tool isn't frozen.
