Result of a preview call (ComputeDelta or ComputeSetOp). Never mutates.
DeltaToken is a server-signed HMAC of { targetListId, source signature, mode, timestamp } with a 5-minute TTL. ApplyDelta will reject any token
that fails to verify, has expired, or no longer reflects current state
(which it detects by re-computing on the server).
TargetListId is null when the operation creates a new list rather than
mutating an existing one (e.g. MaterializeFromView).
