- 引入转场策略系统（`getTransition`），支持 `fixed`、`director`、`rhythm` 三种模式 - 根据账号配置文件动态读取转场配置（`loadTransitions`） - 图片和视频轨道分别调用转场策略，替代原有的固定“闪白”转场 - 支持 `byPosition`（hook/body/keypoint/closing）和 `byDirector` 两种高级选择策略 - 图片动画支持 `loop_animation` 与 `in_animation` 解析（“缩放”、“弹入”等组合） - TTS 合成新增 `rate` 字段（源自账号配置 `ttsRate`），默认语速调整为 1.1 - 默认动画类型从 `kenburns-zoom` 改为 `缩放`，适配中文 CapCut
