P0 修复：配音素材库（voice_library）clip 之前被 GPU 直连路径漏掉，现在单独作为 extra_audio_track 加入 amix P1 修复：无音频流的源素材（如纯视频 mp4）用 anullsrc 静音占位，避免 [i]:a 映射失败回退 CPU（44s） - 新增 clip_has_audio/clip_volumes 参数：_try_gpu_direct 对每个 video clip probe_has_audio + 读取 volume 配置 - 新增 extra_audio_tracks 参数：TTS concat 与 voice_library 整段音轨作为独立音轨 amix - clip volume=0（配音素材库 replace 模式）时原声走静音占位，语义与 CPU 路径一致 - edge_crop_pct>0 时在 GPU 内做四边 2~5% 随机裁剪，恢复随机区间口径 |
