Honour otelContext.active() when starting the agent_session span and when building rootSpanContext, so spans the caller created before session.start() become parents of LiveKit spans. Add a comment to setupCloudTracer explaining that register() uses set-once semantics in the OTel API, so it won't clobber a user's existing context manager or tracer provider. Fixes livekit#924
AudioRecognition was snapshotting rootSpanContext at construction time, so any mutation of session.rootSpanContext after _startSession (e.g. in an Agent.onEnter hook) was invisible to user_turn spans. Store a live reference to the AgentSession instead, and read rootSpanContext fresh on each span creation. Fixes livekit#924
