feat: only play animated trailers before animated content (v1.0.0.11)

An anime trailer could play before live-action content: the genre filter
accepts any single shared genre (anime is tagged Animation + Drama/Action/...),
and when nothing matched it fell back to the whole pool. Trailers tagged
Animation or Anime are now dropped for non-animated features before the
filters and the fallback run, so a live-action feature gets no trailer
rather than an animated one.

 changelog:
-  - Fix trailer downloads, broken by a YouTube change. YouTube no longer
-    serves combined video+audio files, so the built-in downloader now fetches
-    the video and audio separately, merges them with ffmpeg (no re-encode)
-    and deletes the separate files afterwards
-  - A failed download no longer leaves an empty trailer folder behind.
-    Empty folders counted toward "Max trailers to keep" (pushing out real
-    trailers) and were never retried
+  - Animated trailers (anime included) now only play before animated
+    content. Before, an anime trailer could play before a live-action
+    movie or show when they shared a genre like Drama or Action, or when
+    no trailer matched the genre filter. A live-action feature now gets no
+    trailer rather than an animated one
