…arameters. And the extract_struct function supports extracting array nodes.
…tiple PB nodes and assembles them into one RowData. New function extract_struct_excluding(structPath, excludeChild1, excludeChild2, ...) — returns a copy of the struct field with the given sub-nodes removed. Composition extract_binary(extract_struct_excluding(...)) re-encodes the trimmed message as a byte[], allowing bulky sub-nodes to be stripped before being written to a binary sink column. Multi-level protobuf path lookups now reuse cached intermediate node values, avoiding repeated tree descents and improving transform throughput.

Fixes #12117
