This commit introduces a suite of new node selectors to optimize read latency and reduce cross-az costs Changes: - Add `AZAffinityNodeSelector` to prioritize replicas in the same Availability Zone. - Add `AZAffinityReplicasAndPrimaryNodeSelector` for granular control, prioritizing local replicas, then local primaries, before falling back to remote nodes. - Add `PreferReplicaNodeSelector` for explicit routing requirements. - Update `ClientOption` to use strict function types (`ReadNodeSelectorFunc`) for improved type safety.
