feat(core): 添加PSD/PSB图片格式支持并重构媒体文件处理

- 新增ReadPsdImage函数支持PSD/PSB格式图片信息读取 - 修改文件扫描逻辑，将视频处理改为媒体候选处理，使用ffprobe统一判定 - 添加对PSB格式的支持，与PSD共享相同8BPS文件头处理 - 重构handle_image.go中的图片处理逻辑，优化错误处理和记录保存 - 更新文件扫描过滤规则，支持更多图片格式并跳过数据库文件 - 添加文件MD5计算功能用于文件唯一性标识 - 修改媒体处理流程，支持音频文件识别和分类处理 - 移除废弃的视频时长转换函数和相关依赖 - 更新依赖版本并添加SQLite支持用于媒体信息存储
