Search - request/response policies implementation with API overrides

[a-TODO-rov]

Implementing request/response policies for search - version with API overrides
Version with ClusterWriter routing implementation - #3409
Part of #3447

[Copilot]

Pull Request Overview

This PR implements request/response policies for RediSearch in cluster environments, transitioning from cursor ID-based routing to cursor object-based routing with API overrides. The implementation enables keyless RediSearch commands to route randomly across cluster nodes while respecting ReadFrom policies and maintaining cursor stickiness.

Key changes:

• Replaced cursor ID parameters with Cursor objects containing both cursor ID and node ID for cluster routing
• Added cluster-aware routing for keyless RediSearch commands that honor ReadFrom policies
• Updated cursor lifecycle to support sticky routing in cluster mode
