Module signal 

SoftGPU host signals (CPU atomics). No hardware interrupts.

Concurrency invariants

• value and cancelled are atomics; waiters poll both.
• Destroy / queue teardown sets cancelled so waits exit deterministically without requiring the process mutex while spinning.
• SoftGPU does not claim HSA memory-model completeness for foreign AQL producers; SeqCst is a SoftGPU software policy for host-side waits.
