Bound `BroadcastState.cancelled` entries to receiver progress, terminal state and resource lifetime instead of retaining completed `Task`s indefinitely. Deats, - make EOC durable so awakened peers never re-enter a closed source. - close root broadcasters during explicit `MsgStream` and `LinkedTaskChannel` teardown without re-entrant EOC closure or breaking `MsgStream.aclose()` overrides. - reject non-positive fan-out retention capacity before constructing an unusable zero-length queue. - cover child/root cancellation cleanup, terminal peer wakeups, wrapper teardown, subclass compatibility and zero-buffer rejection.
