docs(media): how to file a below-threshold episode by hand

Six single-episode files stayed in the movie library when the threshold refused
them; the hand path is the same executor on a hand-written plan and the same
journal. The trap recorded here is the series year -- never inherit it from the
title whose bonus folder an episode happens to be parked in.
