### Purpose Introduce the `nested_update` field aggregator for pypaimon. This change adds support for the nested_update aggregation function in the Python reader, aligning its behavior with the Java implementation. It supports nested-key based updates, optional sequence-field based conflict resolution, configurable nested-key null handling, and count limiting. ### Dependency This PR depends on #8561 and reuses several shared utility methods introduced there.
