Subject: [PATCH] fix: [zip] improve ARM platform plugin selection for large
 files
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Replace proportion-based logic with size-based thresholds
- Fix uniform large files incorrectly using 7z instead of libarchive
- Add size thresholds: max file > 50MB, total > 200MB, or (total > 100MB && max > 10MB)
- Maintain backward compatibility with original proportion logic

log: 性能优化
