Unknown Walltime execution environment detected

Using the Walltime instrument on standard Hosted Runners will lead to inconsistent data. For the most accurate results, we recommend using CodSpeed Macro Runners: bare-metal machines fine-tuned for performance measurement consistency.

Fix get_buffer_string to support modern tool_calls Fixes #33970 The get_buffer_string() function was still using the deprecated function_call field from additional_kwargs. Modern AI providers (OpenAI, Anthropic, Gemini, etc.) now use the tool_calls attribute instead, causing tool call information to not be output. Changes: - Updated get_buffer_string() to prioritize tool_calls over function_call - Maintained backward compatibility with legacy function_call format - Added tests for tool_calls and priority behavior The fix ensures tool call information is correctly included in buffer strings while maintaining compatibility with older code.
