Module apply 

Pure op-application dispatcher for array CRDT sync.

apply_op is the single entry point for merging an incoming ArrayOp into local engine state. It enforces shape validation, schema-version gating, idempotency, and tile-cache invalidation in a fixed order.

Engine implementations live in nodedb-lite and nodedb; this file ships only the abstract ApplyEngine trait, the outcome types, and the pure dispatcher function.
