fix(#2772): is_settled distinguishes "not finished" from "no such node"

Returning `false` for an unknown id gave the same answer as a node that is
merely still running, so a caller polling a stale id would wait forever for
a state that can never arrive. `Option<bool>` makes the two cases separate,
matching `node()`'s convention that `None` means the id isn't in the graph.
