feat: enrich AniList episode metadata rows

 Rows, metadata and selection prompts label availability UNVERIFIED. Terebi resolves the current selection fresh; unavailable episodes, malformed/protected pages and network failures appear as distinct player errors, while launch/catalog errors remain visible in Tubular. A successful handoff does not mark an episode watched.
 
+AniList episode metadata rows lead with the available series-average runtime (`25 min avg`), format and series year, followed by `sub · UNVERIFIED` and collection/watch markers. Missing or zero average runtimes are omitted. These are explicitly series-level facts, not measured episode durations or individual air dates; legacy Miruro retains its returned episode-specific dates and durations.
+
 Identities are `anilist:<positive decimal AniList ID>:<positive episode>`, with both numbers bounded by Int32. The stable handoff is `https://zokoanime.video/stream/ani/ID/EPISODE/sub` (`ani`, not the broken `anilist` route). Sources, tokens and subtitle URLs are never stored in collections or playback snapshots. Queues use the same stable URL and per-item private progress files; version-2 reports identify `provider = "anilist"`, decimal-string `media_id`, and numeric `episode`.
 
 `anilist-library.toml` stores AniList shows/tags separately from the untouched `miruro-library.toml`. Shared episode collection/state files use exact provider-qualified keys and filter each catalog independently; `miruro:1:1` is not `anilist:1:1`. No opaque Miruro IDs, saved show metadata or old playback sessions are mapped or reinterpreted.
