Folders tagged with a bare IMDb id in brackets (Plex/Kodi style, e.g. '17 Blocks (2021) [tt10011226]') had the id silently dropped — folderIDPattern needs an 'imdb-' prefix and trailingImdbIDPattern needs an un-bracketed trailing tt-id. Recognize bracketed bare tt-ids so these items get the trusted-ID match path instead of falling to title+year scoring.
