- Format string prefers avc1 video + m4a audio, then any codec. The RTX 2070
host can hardware-transcode H.264 but not AV1.
- Pass Jellyfin's ffmpeg via --ffmpeg-location instead of relying on PATH.
- If yt-dlp fails, retry with the built-in YoutubeExplode downloader.
- Read stdout/stderr while yt-dlp runs (and add --no-progress); before,
stdout was never read, so a full pipe buffer could block yt-dlp forever.

YouTube stopped serving muxed streams and YoutubeExplode 6.6.0 failed on
every video ("Video is not available"), so no trailer downloaded. Bump
YoutubeExplode to 6.6.2, download the best video-only + audio-only streams
and stream-copy them into one MP4 with ffmpeg. The separate files are
always deleted afterwards, merge or not.
Also delete the trailer folder when a download fails. Empty folders were
treated as "already downloaded" (never retried) and counted toward
MaxTotalTrailers, so over time they pushed out every real trailer. The
skip check now requires the trailer file itself.

Adapted from Trailers4Jellyfin: keeps TMDB/YouTube trailer downloading,
the scheduled task, language/source/date filters, and trailer rotation,
but drops cinema-mode/IIntroProvider entirely. Each trailer now ships in
its own fake-movie folder (placeholder video + locked NFO + trailer) for
use with a Cinema Mode / trailer pre-roll plugin.
