Added full support for Traditional Chinese (Taiwan). Improved and completed several translations and descriptions to make the app clearer and more accessible. Scanning and document management features remain unchanged.

More reliable scanning: improved edge detection, white-on-white document recovery, difficult-edge handling, optimized tracking and more stable geometry. Automatic scanning: fixed multipage stalls, next-page reacquisition, camera/Vision races and autoscan rearming; automatic mode can remain active for the whole session until manually disabled. Clearer autoscan guidance: AUTO/MANUAL states, progressive instructions, first-use tutorial and post-capture feedback. Image quality: improved lighting, shadow, denoise, sharpening, perspective and crop handling with adaptive, fail-safe processing. Performance and memory: reduced unnecessary copies and decodes; optimized Core Image/vImage/MPS, JPEG processing, stage-2, multipage OCR, caching and persistence. Multipage workflow: incremental OCR, bounded archive writes, original-image memory management and thermal/memory-aware scheduling. Diagnostics: added InfoCam, scanner/session diagnostics, PerformanceDebug telemetry and hardware/camera information. Interface: Light/Dark App Icon, Liquid Glass surfaces in Calibration/InfoCam and complete it/en/fr/es/de localization. Page Review: tap to preview, long press to pick up a page, direct reordering, swipe up to delete and swipe down to archive. Preview carousel: bidirectional scrolling, edge auto-scroll, smoother animations, finger-locked cards and native swipe/long-press gesture arbitration.
