FreeFlix CLI v1.6.2

⬇️ Downloads

• Speed back, clutter gone: HLS uses yt-dlp + aria2c (x16) again for
  throughput, but every fragment + the .part file now go to a temp dir
  (-P temp:) that's deleted afterwards — the Downloads folder only ever sees
  the final .mp4.
• Rock-stable progress bar: the fraction is driven only by yt-dlp's overall
  (frag a/b) count and is monotonic (never jumps backward); aria2c's
  interleaved per-fragment lines feed the speed readout only.

🖥️ Download box is now purely responsive

• The progress box renders in the alternate screen (screen=True), centered:
  resizing reflows it cleanly with no offset/leftover, and it erases itself on
  exit.
