创建 FACE 表情消息

FACE 消息只携带表情标识和尺寸，不上传图片。宿主根据 themeName 和 stickerName 映射自己的表情资源。

suspend fun createFaceMessage(
    name: String?,
    themeName: String,
    stickerName: String,
    width: Long,
    height: Long,
    isGif: Boolean,
): BimFaceMessage

val message = BimImManager.getInstance().chatService.createFaceMessage(
    name = "01",
    themeName = "default",
    stickerName = "01",
    width = 240,
    height = 240,
    isGif = false,
)

创建后使用统一的 sendMessage 发送。SDK 不负责表情资源下载、缓存或展示。
