FreeFlix CLI v1.6.1

🐛 Downloads

• No more fragment clutter: HLS now uses yt-dlp's native parallel-fragment
  downloader (--concurrent-fragments 16) instead of handing each fragment to
  aria2c — which was spawning hundreds of *.part-FragN / *.aria2 files in
  the FreeFlix folder. One .part file now, renamed to one .mp4.
• Stable progress bar: it tracks the overall download (frag a/b), not the
  tiny per-fragment files, so it starts clean and climbs smoothly to 100%.
• Leftover fragment/temp clutter is swept before and after every download.
• aria2c is still used for direct .mp4 (single file, multi-connection).

🔙 Back navigation everywhere

• Every season / language / episode picker now has a ← Back that steps up
  one level (episode → language → season → out), so you can back out without
  finishing the whole flow. Applied to Anime-Sama, Coflix, French-Stream,
  French-Manga, GoldenMS, GoldenAnime.

✨ Launch

• The startup splash now plays a short, smooth 0 → 100% sequence instead of
  flashing past.
