BREAKING CHANGE: Complete refactoring of the conversion pipeline. - Replace in-memory Page/PageContainer with disk-based PageFile struct - Extract archives to temp directory instead of loading into memory - Use cwebp InputFile/OutputFile for zero-copy file-to-file conversion - Use cwebp -crop for splitting (no Go-side image decode needed) - Check if already converted before extracting (fast pre-check) - Remove oliamb/cutter dependency (replaced by cwebp -crop) - Remove page_container.go (no longer needed) - Add comprehensive tests with improved coverage Co-authored-by: Belphemur <197810+Belphemur@users.noreply.github.com>
