Spreen — the falcon's stoop, then the preen. Walks the current directory for media files with a given extension and rewrites their filenames so the space after the track number becomes a configurable delimiter and `N-` disc prefixes become `DiscN/` subdirectories, dry run by default, via the track-delimiter CLI.
