Walkthrough

inviteFriendToRoom에서 초대 DM 본문을 기존의 단순 문자열 대신, 방/호스트/영상 메타데이터를 포함한 contentObj(JSON)로 구성하여 저장하도록 변경되었습니다. contentObj에는 roomId, roomName, hostNickname, hostProfileImage, hostPopularity, currentParticipants, maxParticipants, videoTitle, videoThumbnail, duration, isPrivate, message 등이 포함되며, 영상 관련 필드는 없을 경우 빈 문자열로 대체됩니다. 알림 생성, 초대자/영상 조회, Socket.IO 전송 구조와 흐름은 그대로 유지됩니다. 공개된/내보내는 API 시그니처 변경은 없습니다.
