Pull Request Overview

This PR optimizes the get command by reducing gRPC calls and adds test coverage for the command. The optimization attempts to run the get command normally first, and only falls back to using force_output if no response is received, potentially reducing unnecessary gRPC overhead.

• Optimized the get command to avoid unnecessary force_output calls when a response is already available
• Added test coverage for the get command to ensure it works correctly when muted
• Fixed existing test structure by adding proper muting context
