The "Task#suspend doesn't raise" test left its task parked in
q_suspended_. A later test ("Task.run inside Task.run is a noop")
calls Task.run, and the scheduler will not exit its loop while any
task sits in the suspended (or waiting) queue, so the whole run
hung.
Terminate the task at the end of the suspend test so it does not
leak into the shared scheduler state the next test depends on. This
fixes the hang at its source rather than scrubbing leaked tasks from
the consumer side.

- This patch implements `Task::Queue` mirroring `Thread::Queue` in CRuby.
- Producer/Consumer pattern is now possible with no polling
## No Top-level pollution
- No top-level `Queue` defined
- No `TaskError`. Instead, `Task::Error` happens when `Task::Queue#pop(true)` when empty
- No `ClosedQueueError`. `Task::Error` also happens when pushing to closed queue
## Future Work
- `Task::SizedQueue`
add tests for sleep/usleep validation, task creation, status/inspect
methods, control methods, task.stat, priority handling, and name
handling.
