Add a `deferred` flag to `TestChainMonitor` that controls whether the underlying `ChainMonitor` queues operations instead of executing them immediately. The flag is derived from the fuzz input alongside the existing monitor style bits, so each of the three nodes can independently run in deferred or immediate mode. In deferred mode, `watch_channel` and `update_channel` always return `InProgress`. A new `flush_and_update_latest_monitors` method drains the queued operations and, when the persister reports `Completed`, promotes the pending shadow monitor snapshots to persisted state. This method is called before `release_pending_monitor_events` and at each point where the fuzzer completes pending monitor updates. On node reload, deferred monitors are flushed immediately after `watch_channel` so the node starts with a consistent state. AI tools were used in preparing this commit.
