video2slides: 重构为纯客户端 app（浏览器抽帧 + IndexedDB），后端归零

- 不再上传视频：<video>+canvas 原生解码按时间戳 seek 抽帧，逐帧 256px 灰度 MAE 算差异，缩略图(320)+大图(1280) 随抽随写 IndexedDB，带进度条+ETA - 阈值/手动保留弃用/缩放偏好持久化到 IndexedDB，刷新仍在 - PDF 导出回到客户端 jsPDF，保留帧逐张 base64 嵌入、单帧处理防 OOM - 后端删光业务逻辑（core.rs/handlers.rs），main.rs 缩成 cube_core::base 静态服务 - 不再需要 ffmpeg → Dockerfile 回归 FROM scratch；k8s 去掉 hostPath 卷、降资源 - 真浏览器(Playwright)验证：抽帧/差异/阈值/持久化/导出全通过
