Episode gains an additive absolute field services can set, an {absolute}
naming token (3-wide), and an --enrich fill from TVDB's absolute order
that never rewrites season or episode numbers.
--anilist supersedes --animeapi (REST: anilist_id); the keyless AniList
GraphQL provider joins the registry with title search, mal: ID lookup,
an ANILIST mkv tag, and the anilist_title_language config option.
Services mark anime via Service.ANIME / Title.anime for anilist-first
metadata resolution with fall-through.
Supplied IDs resolve directly via a shared resolve_by_ids and never fall back to title search; metadata_providers gains per-kind ordering and a disable_metadata switch stops all automatic lookups while explicit IDs keep working.
BREAKING: --tmdb/--imdb/--tvdb are now mutually exclusive and require a usable provider; --enrich also overwrites original language; the imdbapi provider and imdb_api_enabled are replaced by a keyless imdb provider.
--enrich now sets Title.language when the service left it unset, so video tracks stop falling back to und. Adds original_language to MetadataResult (TMDB, TVDB, OMDb, IMDxAPI) and falls back to OMDb for --imdb, which previously did nothing while imdb_api_enabled defaults to false.
subtitle.language_priority and audio.language_priority prepend to the CLI
languages, so the named languages sort first and nothing is filtered.
--exact-lang now applies to the sorts too, through matching_languages, which
follows the same RFC 4647 rule as Tracks.by_language and ignores invalid tags.
Document tvdb_api_key, tvdb_pin, tvdb_order and metadata_providers, the
--tvdb and --tvdb-order flags with their behaviour when an order does
not cover a whole series, the new REST API parameters, and the Matroska
TVDB2 tag prefixes.
Only fall back to Title.language when the manifest labels nothing, and reject und as firmly as a missing tag. Exported direct-URL subtitles now replace the re-parsed set, and fetch failures stay distinct from parse failures.
Share one best-audio selector across the episode and music paths so best/all works for songs, descriptive audio is capped to one track, and codec_priority is honored. Guard --channels and 16:9 canvas math against tracks missing channel/width metadata. Extend --best-available to video languages and full resolution misses in both normal and hybrid mode, and count only deliverable ranges when reporting missing resolutions. Rank video by resolution before bitrate, and trim group audio selections to one track per song with a warning.
BREAKING CHANGE: a missing resolution with -r HYBRID now errors without --best-available, matching non-hybrid behavior.
