- tag mode: when no German-tagged audio track is found but the release name
says German/Dubbed, fall back to the first track (the dub is mislabeled, e.g.
German tagged "eng") instead of skipping; non-German names still skip safely
- comprehensive logging: per-package ffmpeg/ffprobe availability, plus per-file
detected audio languages, decision + reason, remux/rename result and the exact
error text when a file can't be processed
- shorter same-dir temp name so a long scene path + temp suffix cannot exceed
Windows MAX_PATH and silently fail the remux
