Catchup-request helper: tracks the last-seen inbound HLC per array and
builds ArrayCatchupRequestMsg messages for the transport layer.
§Persistence
Each per-array last_seen_hlc is persisted under Namespace::Meta with
key b"array.last_seen_hlc:{name}". CatchupTracker::load restores all
entries on startup so the first catchup request after a restart asks only
for ops the device has never seen.
Structs§
