Cross-process against the real arr binary, real ffmpeg and real alass:
a provider fetch synced and named under DESIGN.md §15, never
re-searched once satisfied; an embedded English track extracted and
translated into a .mt sidecar; an implausible sync kept unsynced and
surfaced in the missing-subtitles queue. Podnapisi and the translation
backend are stubbed at the HTTP/process boundary, never a live tracker
or a live translation API.
Daemon::spawn_with_env for extra child environment, database_path()
and media_root() accessors so a test can seed a media file directly,
the daemon built with translate-command, and the plausible/farfetched
Podnapisi zip fixtures the subtitle tests download from.
Nothing drained AppState's movie_commands mpsc, so manual search and
one-click grab were accepted with 202 and then did nothing until the
64-slot buffer filled and the endpoint started 503ing.
A new daemon task drains it: Search resets the movie's backoff and
runs the targeted-search + grab lane immediately; Grab sends the
already-chosen release straight to Transmission.
