Require explicit seeds for `Simulation` and `SimulatedEnvironment` to ensure reproducible test results. Also: - Drop packets in `FakeUdpSocket` when the receive queue is full to prevent unbounded memory growth during stress tests. - Improve synchronization in `Simulation::run_until` by adding a timeout to the barrier wait, preventing hangs if a runner is unregistered.
