Code Review

This pull request introduces a comprehensive system for identifying and deduplicating music albums, featuring a desktop application built with Electron, React, and FastAPI. The core logic includes a sophisticated comparison engine that combines algorithmic scoring, a local machine learning model, and optional AI analysis via Gemini. Key backend components handle recursive folder scanning, metadata extraction, and quality assessment. The frontend provides a modern RTL interface for reviewing clusters and managing deletions safely. Feedback from the review identifies a logic error in the folder scanner that would skip directories containing subfolders and a structural issue in the dummy image processor used when Pillow is unavailable.
