Proxies should honor MethodShapeAttribute.Name

[Andrew Arnott (AArnott)]

RPC targets already honored this attribute, so it's critical that proxies do as well, so that when proxies send requests, the servers will match them to a method.

Fixes#1267

Pull Request Overview

This PR enhances JSON-RPC proxies to honor the MethodShapeAttribute.Name property, ensuring consistency between proxy clients and server targets that already supported this attribute. This prevents mismatches when proxies send requests to servers that use renamed methods via MethodShapeAttribute.

• Adds support for MethodShapeAttribute.Name in proxy method name resolution
• Updates metadata classes to track MethodShapeAttribute information
• Adds comprehensive test coverage for the new functionality
