Snapshot
A state-machine snapshot. Opaque to kuilt-raft — it never deserializes state; only the consumer can collapse many log entries into compact state. The same payload flows both directions: the consumer publishes it via RaftNode.snapshots (outbound), and a lagging node receives it wrapped in Committed.Install (inbound).
Parameters
throughIndex
the highest committed log index this state reflects.
state
opaque application bytes.
