Add OTEL tracing to the sampling pipeline: - `sampling/createMessage` span wrapping sample_impl() with attributes for temperature, max_tokens, tool_count, result_type, and iteration count - `sampling/createMessage step` child spans per loop iteration with iteration index and stop reason - `sampling.execute_tool <name>` spans for tool calls within sampling, including error status on failures - Validation failure and text response retry events on the parent span - Opt-in content capture via OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGE_CONTENT Also adds is_recording() guards to server_span, delegate_span, and client_span to avoid unnecessary attribute serialization when sampling is disabled, and sets error.type using __qualname__ for better nested class names.
