ancaferro/myPhotos ? reverse-engineered prompt

Build me a desktop app for managing a photo folder that can scan images recursively, find faces automatically, and group the same person across the library.

I want to browse the photos in a clean gallery, click a person on the side to filter everything to that face, and open any photo in a full size viewer where all detected faces are outlined and labeled. Let me rename people, merge duplicates, split a face into a new person, or delete a wrong detection, and make sure those edits stay saved even after I run the scan again. It should also let me add my own tags to photos, sort by filename or capture date, show basic location info from the photo data when it exists, and keep thumbnails cached so reopening a big folder feels fast.

Use a simple desktop UI, save everything in a local SQLite database, and make the folder recheck itself when files change. If you need current docs for the face detection models or PySide6, look them up online first.
