feat(tag-input): IR-style kind:name suffix — drop the kind dropdown from TagAutocomplete; client-side parser mirrors backend's parse_kind_prefix (KNOWN_KINDS = artist/character/fandom/series/meta/rating); autocomplete searches across all kinds and shows kind chip in results; Create label uses parsed kind; character flow still goes through FandomPicker
