* fix(studio): a slow thumbnail job keeps a reader that other clips still decode from A job that timed out judged the reader by its own progress only. A poster job that got an already-open reader while a sibling was decoding on it, and took more than its budget to reach its one frame (a slow link, Chrome's six connections held), logged a timeout and retired a healthy reader, so the next clip re-read the index. The pooled reader now counts the frames every job decodes from it, and a timed-out job retires it only when no frame came from it while the job held it.
