dashwire_replication 0.2.1

• Replica.snapshotTick, the server tick of the newest snapshot that carried a replica's state. A predictor reconciling against replicated state pins it to this tick rather than to the input ack, which runs every tick while snapshots are budget-packed and can be deferred or dropped.
• ReplicationClient.inputLeadTicks exposes the adaptive send-ahead lead, so a caller passing an explicit tick to sendInput can pace from it instead of stranding the buffer-depth control loop.
