Implement the approved PR #481 child-reap bookkeeping update after the
preceding `Context.cancel()` fix was committed separately.

> `git diff HEAD~1..HEAD -- tractor/runtime/_supervise.py`

`ActorNursery._mark_child_reaped()` captures both reap-coordination
entries and asserts that they are either both present or both absent.
It intentionally does not require the reap-request event to be set,
because backend cancellation can reap immediately after registration.

> `git diff HEAD~1..HEAD -- tests/test_to_actor.py`

Existing real-runtime graceful and hard-reap tests verify that
`ActorNursery._children`, `ActorNursery._child_reap_requests`, and
`ActorNursery._child_reaped` are all empty before the one-shot call
returns.

Run focused bookkeeping and real-runtime reap tests after the edit.
