_chat_ctx_to_otel_events only mapped system/user/assistant roles, so ChatContext items with role="developer" were silently dropped from the OpenTelemetry span events and invisible to any downstream tracer. Map developer to EVENT_GEN_AI_SYSTEM_MESSAGE since OpenAI's developer role is the successor to system on the Chat Completions API and carries equivalent instructional content. Fixes livekit#5398
