The `// SAFETY:` comment in NodeDeath::set_cleared assumes that a NodeDeath is never inserted into the death list of any Node other than its owner. However, this invariant is not enforced by the safe function Node::add_death, which inserts NodeDeath into the death list without checking that death.node == self, leaving a risk for future code that may miss this implicit invariant and cause undefined behavior. Add an assertion to make this precondition explicit and catch potential violations early.
