💡 What: Modified handle_json_rpc_message, handle_tool_call, and execute_tool to take &AppState rather than AppState.

🎯 Why: To eliminate an unnecessary .clone() call on the AppState inside the inner loop of handle_json_rpc when handling batched JSON-RPC messages.

📊 Measured Improvement: Created a baseline benchmark using Criterion mimicking the AppState cloning loop. The baseline loop_with_clone took ~1.41µs to process 100 items, while the optimized loop_with_borrow implementation using references completed in ~53.8ns, achieving an approximately 26x performance improvement.

The benchmark was imported incorrectly resulting in rustfmt failing on CI. This commit runs cargo fmt --all to fix it.

Replaced deprecated criterion::black_box with std::hint::black_box to resolve build errors with `-D warnings`.
