Module executor 

Priority-aware async executor with single-stack task polling.

All cooperative tasks share one system stack. The executor polls tasks in priority order. When a task returns Poll::Pending, its state lives in a static TaskCell referenced by the task’s TaskReg.user_data — no per-task stack allocation is needed.

When all tasks are pending, the executor calls port::arch::idle() to enter a low-power state.
