Include the tool arguments in instrumentation callback data when tools/call is invoked. This allows consumers to track which arguments were passed to each tool call for analytics and debugging purposes.

Follow-up to #218, which added the `tool_arguments` feature to the instrumentation callback. This updates README.md to document the new `tool_arguments` key in both instrumentation callback sections, and removes redundant instrumentation documentation.
