Pull Request Overview

This PR adds a proxy job functionality to the RedCarbon agent. The primary purpose is to enable the agent to fetch HTTP requests from the server and execute them as a proxy, then submit the responses back.

• Added new protobuf message types for proxy requests and responses
• Implemented new gRPC methods for fetching agent requests and submitting responses
• Created a background proxy routine that polls for requests and processes them concurrently

• [nitpick] A 200ms polling interval could generate excessive load on the server. Consider increasing the interval or implementing a push-based mechanism for better performance.
