Whether an update is worth sending to other server instances.
Streaming content is excluded. It arrives at hundreds of messages per second and each one carries
a full serialized agent run, so replicating it would cost far more bandwidth than the delivery it
buys — and a token delta is worthless to a client that has already missed the ones before it.
Progress and completion are low-rate and each is individually meaningful, which is exactly the
kind of message that must survive landing on the wrong replica.
