Module time 

Async timer primitives: [sleep], sleep_until, [interval].

All timers are driven by a per-thread hierarchical timer wheel integrated into the executor run loop. The wheel is ticked each iteration of the loop; expired timers fire their wakers, re-scheduling the waiting tasks.

Thread-local timer wheel

The TIMER_WHEEL thread-local holds the wheel for the current executor thread. with_timer_wheel provides safe, borrow-scoped mutable access.
