feat: cascade retry deps when running a task with failed dependencies

When /run is called on a CANCELLED/FAILED task that has deps in a terminal
failure state, automatically reset and resubmit those deps so the task
isn't immediately re-cancelled by the pool's dep check.

Also update reset-failed-tasks script to handle CANCELLED tasks and clean
up preserved sandbox workspaces.
