### Performance

- Clipboard images are now stored compressed with SwiftData external binary storage: already-compressed captures (PNG/JPEG/HEIC/GIF/WebP) are kept as-is, uncompressed TIFF captures are re-encoded to PNG, and oversized images are downsampled. This dramatically cuts memory and disk usage for image-heavy histories that previously grew to well over 1 GB.
- Every image read — thumbnails, previews, OCR, barcode scanning, Quick Look, export, and copy — now loads the bitmap through a short-lived context and releases it right after, so full-size images are no longer kept resident in memory.
- Existing image history is migrated to the new compressed storage in the background on first launch.

### Fixes

- Fixed a crash that could occur shortly after launch on image-heavy histories.
- Kept image paste broadly compatible by attaching a TIFF flavor for non-PNG/JPEG formats.

### 性能

- 剪贴板图片改用压缩格式 + SwiftData 外置二进制存储：已压缩的截图（PNG/JPEG/HEIC/GIF/WebP）原样保留，未压缩的 TIFF 截图转为 PNG，超大图先降采样。图片较多、以往会涨到 1 GB 以上的历史，内存与磁盘占用大幅下降。
- 缩略图、预览、OCR、条码识别、快速查看、导出、复制等所有图片读取，改为按需用短生命周期上下文加载并随即释放，不再把整张大图常驻内存。
- 已有的图片历史会在首次启动时于后台迁移到新的压缩存储。

### 修复

- 修复图片较多时启动后不久可能出现的闪退。
- 回贴非 PNG/JPEG 格式图片时附带 TIFF 兼容格式，保证粘贴到各类应用的兼容性。
