/**
 * Get native RTC stats report from peer connection(s).

 * LiveKit supports multiple PC modes:
 * - publisher-only: single PC for both outbound and inbound
 * - subscriber-primary / publisher-primary: separate PCs
 *
 * This method handles both cases by checking if subscriber PC exists.
 *
 * Note: This uses LiveKit's internal API (room.engine.pcManager) which may
 * change in future versions. If this breaks, update the path or fallback
 * to track-based stats collection.
 *
 * @returns RTCStatsReport containing stats for all tracks
