+form used by the title search: multi-word prefix tokens by default ("Ma Ca Ju" finds *Man who jumps

 `media-scrape/src/filter-presets.ts`: aspect buckets (vertical, square, 4:3, 16:9, 21:9, other) and
 resolution buckets by the shortest side (SD, HD, FHD, QHD, 4K+, unknown). A missing resolution is
 filled with `ffprobe` after a download when `VESKSLOP_FFPROBE` is available.
