Torznab tvsearch already existed; what was missing is choosing it per
indexer. `t=caps` says which parameters a tracker takes, so a TV target
now degrades: tvdbid where supported, the widest selector the indexer
accepts, text search where it does ID lookups at all.
Widened searches return packs beside single episodes, so release names
carry a season/episode claim: numbered episodes, season and multi-season
packs, multi-episode files and daily air dates.
