Detailed Description

Mixed fanout policy that allows one consumer plus any number of copies.

A node marked with this policy may have direct children that use prev access only under the following rules:

at most one direct child may use consume_prev;
every other direct child that uses prev access must use copy_prev;
borrow_prev and borrow_prev_mut are not allowed.

At runtime the executor stages the fanout before children begin execution: copy payloads are materialized first for copy_prev children, and the original upstream payload is then reserved for the single consume_prev child. This keeps the semantics independent of sibling execution order.
