…ase 6.5) WebSocketCopilotTarget accepts trace_config. With tracing enabled, each send records a fresh request trace context, sends its trace ID in the prompt payload's own traceId field, and sends traceparent on the WebSocket handshake. Tracing stays off by default, the per-request requestId stays separate from the trace ID, and a stale link on a reused request is cleared.

Second target for phase 6.5, following #2945 for
LiteLLMChatTarget.WebSocketCopilotTargetnow acceptstrace_config. WithTargetTraceConfig(enabled=True), each send records a fresh request trace context through the sharedtarget_trace_contextpath, carries its trace ID in the prompt payload's owntraceIdfield (previously a random value equal torequestId), and sendstraceparenton the WebSocket handshake.requestIdstays a separate per-request value. Tracing is off by default, and a stale link on a reused request is cleared, as for the other targets.Tests cover a fresh context per request reaching both the handshake header and the payload, tracing off by default and with
enabled=False, and the link not being copied onto the response. Each fails with its part of the change removed. ruff and ty are clean, and the prompt target suite passes.
