/**
* Write each node as its current state, replacing the stored record.
*
* The merge path (`cstx_graph_add_nodes`) owns bulk ingest and keeps its JSON
* fast path. A replace batch is a caller restating records it already holds —
* a task's oracles, a document's current revision — so it goes through the
* shared `Value` path rather than earning a second parser.
