Pull request overview

This PR corrects a bug where the wrong attribute key was used when extracting tool response attributes for OpenTelemetry tracing. The method getToolResponseAttributes was incorrectly using AGENTSCOPE_FUNCTION_INPUT instead of AGENTSCOPE_FUNCTION_OUTPUT.

Key Changes:

• Fixed attribute key in getToolResponseAttributes from INPUT to OUTPUT, aligning with the established pattern where request methods use AGENTSCOPE_FUNCTION_INPUT and response methods use AGENTSCOPE_FUNCTION_OUTPUT
