Handle [TAG] NN episode-only filenames: when a file already
carries a bracket tag prefix followed directly by an episode
number (e.g. [WBDP] 03 - Deus Vult), inject the show name
from the parent folder between the tag and the episode part.
Also update ExtractShowName to handle bracket-style folder
names (text before the first [ is the show name).
