enableDeltaSync property
Whether the pull phase may use incremental pulls when the remote
adapter mixes in DeltaSyncCapable — fetching only entities modified
since the last sync watermark instead of the full dataset.
Defaults to true (the capability mixin is itself the opt-in). The
engine still performs full pulls for a user's first sync and for cycles
that need the complete remote id set (detectRemoteDeletions).
