Python SDK v8.0.0

Changed (breaking)

• client.traces.get (TraceDetail) now returns a single conversation field — the full trace conversation in OpenTelemetry GenAI format: the system instructions, then the running message history sent into the trace's last LLM-completion span, followed by that span's generated output. The previous system_instructions, input_messages, and output_messages fields are removed. They only captured the first turn's input and the last turn's output, silently dropping every intermediate turn and tool call — all of which conversation includes.
