ObjectMergeStrategy class

A MergeStrategy that treats each document as a single, atomic CRDT record.

Concurrent edits to the same document resolve last-write-wins as a whole: the edit with the higher Hybrid Logical Clock wins entirely and the other is discarded. Edits to different documents always both survive.

This is the default strategy. Choose it when a document has cross-field invariants that a partial merge could violate.
