When LeRobot video fallback runs in a worker thread, it loses the caller's
no_grad()orinference_mode()setting. Capture both Torch modes before dispatch and restore them for each decode task.Added a single-camera regression that checks normal, no-grad, and inference modes on a reused decode pool. LeRobot tests: 96 passed, 1 skipped; Flake8 passed.
