Purpose
Introduce
nested_partial_updateaggregator functionThis change adds support for the
nested_partial_updateaggregation function in the Python reader, aligning its behavior with the Java implementation. It supports nested-key based partial updates, where only non-null fields overwrite existing values, while configurable nested-key null handling ensures consistent behavior with the Java implementation.Dependency
This PR depends on #8577 and reuses several shared utility methods introduced there. Please review and merge #8577 first.
