* fix(filer.sync): guard batched events against nil EventNotification The server folds a backlog into one response: the first event in the top-level fields, the rest in resp.Events, and the pipelined sender can drain an idle heartbeat (nil EventNotification) into that tail. Only the envelope got the freshness-signal guard, so a batched heartbeat reached AddSyncJob and nil-derefed in IsEmpty while replaying a backlog buffered during a peer outage. Route every event, envelope and batched, through one handler that sends freshness signals (nil heartbeat, empty marker) to OnIdleHeartbeat. * fix(filer): guard MetaAggregator batched events against nil EventNotification The peer subscription's envelope is nil-guarded but its batched tail was not. The aggregator doesn't enable idle heartbeats today, so the server can't fold a nil EventNotification into the batch yet, but make the two loops consistent so it can't nil-deref if that changes.
